One of the nice things about Prime is that there is lots of food, about 3 seconds away. Since this is definitively NOT TRUE around the BCEC, this thread attempts to inform you of the available choices, along with estimated travel times.
FOOD FOR DUMMIES
Foodler - Delivers food to everywhere. As many as 80 options. All price ranges and culinary styles.
Note about walking times: I'm measuring from the front entrance of the BCEC. If you've never been there, be prepared to take as many as 15 minutes to get from wherever you are to the doors. I'm using Google for the walking times - so adjust accordingly. Keep in mind it will probably be brisk out, especially in the evenings.
WALKING DISTANCE
0 Minutes - Food Court
In the BCEC
Hours: ?? - will be in program.
Yes, it's expensive, perhaps even overpriced. But it's close by.
1 Minute - MJ O'Connors Irish Pub
Located conveniently in the Westin - connected to the BCEC
Hours: 11:30am - 12pm
Possibly less expensive than the food court. Rather slow and the food quality is extremely variable.
"I found MJ O'Connors Irish Pub to be irish bar food, not great not bad, the drinks were as reasonably priced as hotel bars get." ~zepherin
1 Minute - Sauciety (Hotel Grill)
Located conveniently in the Westin - connected to the BCEC
Hours: 7am - 2:30pm
Very expensive - think hotel grill ($25 entrees)
5 Minutes - Morton's Steakhouse
Located in the Seaport World Trade Center complex (other side of the pedestrian bridge)
Hours: Friday 11:30am - 11pm, Saturday 5:30pm - 11pm, Sunday 5pm - 11pm
REALLY F***ING EXPENSIVE - think $60 entrees. But delicious. A little ritzy.
7 Minutes - The Whiskey Priest (Irish Pub)
Located at the intersection of B and Northern Streets
Hours: ??? - emailed them to find out
Standard Bar food prices. Standard Irish Pub menu.
7 Minutes - Atlantic Beer Garden (Pub)
Located next to the Whiskey Priest - B and Northern Streets
Hours: 11:30am - 2am, must be 21 after 9pm.
Bar food, bar prices.
8 Minutes - Del Frisco's Steakhouse
Located at the intersection of D and Northern Streets
Hours: 5:30pm - 11pm
REALLY F***ING EXPENSIVE, again. More ritzy than Morton's.
8 Minutes - Legal Test Kitchen (Seafood)
Located on D street, close to the harbor.
Hours: 11am - 2am
Expensive, but worth every penny. The famous Legal Sea Foods, but cheaper, and with interesting new dishes.
"The food was delightful, the atmosphere was trendy and classy, and the alcohol was wonderful." ~Onmitsu
9 Minutes - Dunkin' Donuts (Coffee and Donuts)
Located at the Seaport World Trade Center
Hours: 5am - 12 am
Ubiquitous coffee chain. "America Runs On Dunkin", etc. However, don't buy their baked goods after 12, as they get stale.
10 Minutes - Salvatore's (Italian)
Located on Northern Street, around the corner from Legal Test Kitchen
Hours: Friday 11am - 12am, Saturday 12pm - 12am, Sunday 4pm - 10pm
Standard restaurant prices, delicious Italian food. People go there both dressed up and not.
10 Minutes - Sal's Takeout (Pizza & Sandwiches)
Located next door to Salvatore's
Hours: ??? but presumably similar to Salvatore's
Cheap delicious pizza. A delicious slice the size of your face (1/4 19" pizza) for something like $4.
So, that's the "within 10 minutes" area. Boston, however, has a lot of delicious food options, that are only a T ride away! (See the next post for some recommendations.)

Map of Local Environs - may not be current, and doesn't have everything listed here, but has other options, including touristy sites and bars.

Also, crowdsourcing! Anyone who has any recommendations, for either nearby or less nearby places, post and tell me, and I'll add them to the OP. I'm magical, but only to a certain extent.

Thank you to everyone who has made suggestions!
Happy Eating!

Note about distances - These are listed as N minutes from a T Station. I will also include the addresses. Yes, you can walk to some of these places, but you get to figure out how to do so yourself. :P If you're curious about subway travel time, The Official MBTA Website has a route planner that's pretty accurate.
7 Minutes from South Station - Windsor Dim Sum Cafe
Chinatown - 10 Tyler St, Boston, MA 02111 (between Beach St & Kneeland St)
Hours: 9am - 10pm
Inexpensive; "It's a sit-down and order style Dim Sum, but everything we were served was absolutely delicious." ~Angrypasta
in short, foodler is amazing, and is a paxer's bff.

There's a couple of restaurants in the Seaport Hotel, also. Tamo Bar was a little slow and more than a little expensive, but the food wasn't too bad.
Also, about the Legal Test Kitchen, my friends and I had our pre-pax dinner there, and were immensely pleased. I'm almost 100% going to reserve a table for us there this year again. The food was delightful, the atmosphere was trendy and classy, and the alcohol was wonderful. It's not a cheap meal by any means, but if you want a memorable meal to kick off your PAX East, it's a place I'd recommend.
Also, if you're skipping out on the inevitable PAX East Dim Sum event (or even if you're not), check out Windsor Dim Sum Cafe in Chinatown. It's probably like a 15-20 minute walk from the BCEC, but it was worth it. It's a sit-down and order style Dim Sum, but everything we were served was absolutely delicious. Small place, though they asked us if we wanted to sit at our own table or share one with others. I'm looking forward to going back here.
Places to avoid(?): The No-Name Restaurant. Maybe we just ordered the wrong thing, but me and my friend ordered the "Lobster Special" and it was both the most expensive and awful thing I've ever eaten in a restaurant. My friend shared this opinion. Service was lousy, but the place looked like it could accommodate a lot of people. YMMV.
I found MJ O'Connors Irish Pub to be irish bar food, not great not bad, the drinks were as reasonably priced as hotel bars get.
I was tempted to point people towards last year's thread but I would put more faith in this one since it seems to have more PAX XP (BCEC expansion).
Are you referring to the Atlantic Beer Garden? It's wasn't bad, I went there with some PAX train folk for pre-PAX dinner. They go a little beyond standard bar food with a lot of beer options, a solid choice.
Generally, if you want a good variety, you'll have to get into downtown Boston.

^ things I like
Bunneh approves.
A list of things, should you be of the gifting persuasion
No, I went there, and it was amazing, but this place was literally down the street. Where you took the left to go to Whiskey Priest and ABG, you crossed the street forward and it was right there.
you just type in your address (or, more likely, the address of the hotel at which you are staying) and you will be presented with a list of places that deliver to that location. you can then click on any place in the list to view the menu and order online directly through the site. just make sure when you are ordering food from a hotel that you include your room number with the address so the front desk can call you when your food has arrived.
7 Minutes - Atlantic Beer Garden (Pub)
Located next to the Whiskey Priest - B and Northern Streets
Hours: 11:30am - 2am, must be 21 after 9pm.
Bar food, bar prices.
My note for this restaurant is after a certain time (think it was 11pm but don't quote me) it turns into a nightclub, which is the case on the two restaurants next to it (can't remember the others names after discovering Sam Adams Brick Red at the Atlantic Beer Garden). Which made it 21+ age requirement, so for anyone under 21 you may want to keep that in mind.
This place wasn't bad to eat, the macaroni and cheese burger was decent, I will say I covered the tab for me and 3 other people and it was close to 300 bucks when we finished eating/indulging, but I guess thats all relative to the person.
I remember the bar. It had just opened up and wasn't open long enough for anyone to have put it on the original map. For reference, from the Westin/BCEC, walking across the bridge towards Legal Test Kitchen, just keep going straight and it was by the water. Pretty good burgers. We stumbled upon it Thursday night for dinner and while looking for J. Pace to scout out breakfast foods for the rest of the weekend (which kept us very happy except Sunday morning when it was open later than we expected).
YES. That's the place... I'll google the area and see what I get...
8 minutes - Jerry Remy's Seaport (Sports Bar and Grill)
Located at 250 Northern Avenue (Across from LTK)
11am to 2am all week, 21+ after 9pm
A little more upscale than the average sports bar (Cheeseburger with sweet potato fries and a 16 oz Sam Adams runs you $16)
Amazing Burgers, Tons of beer on tap (including many Massachusetts locals), Monster Video wall (an 8x4 grid of 46" plasmas)
I've been to the one over near Fenway Park. It's a great place! Definitely on my recommend list. Especially seeing as on Saturday afternoon of East is the last Bruins home game of the season.

Anybody with specific dining requests can feel free to ask me, I have 10 years of serious eating in Boston under my belt (oh look, a bad joke). I will admit - I haven't been to Menton or Ten Tables yet, but short of that ... I'm sure Juju and a few others will chime in as well.
Closing note - I would strongly suggest going to Chinatown for at least one meal, even if it's a bit of a walk vs what's right on the waterfront. It's cheap and delicious, plus you'll be able to find a place where you can sit down without a wait.

Did we ever talk about the possibility of food trucks @ BCEC? I know I wanted to float the idea by you to see if could put it in the right hands. There's a solid number of them in town and I'm sure the prospect of a convention center full of hungry folks would cause at least a few to set up shop.

a little closer to the latter than I'd care for

Last year there was an organized group that went there for a dim sum brunch on Sunday morning and it was fantastic. I forgot who was in charge of it, but I'm keeping an eye out for it again.
@Durinthal
*ears perk up* PAX dim sum? That should definitely be a thing.
Possibly a dumb question but were there any good soup dumplings in Boston's Chinatown?
2009 Omeganaut
Gourmet Dumpling House, Dumpling Cafe, and Taiwain Cafe all have decent soup dumplings.

Hello! Are there any Indian restaurants you'd recommend? (Delivery or dine in.)
Thanks!
