Other places
Kelly's Sq Pub
Bennington st - this place may not look inviting from the outside small windows, but inside it is a bright family restaurant. it is mostly locals, but very clean and the waitstaff is very friendly. the food is standard bar fare with very large portions. wednesday is half price pizza day pretty good pizza, especially the garlic pizza. we always take home half our meal and it is good for lunch the next day. it is probably the best, non-dive bar to watch the sox game.
There are also a few old school bakeries that make fresh bread daily. The one locals go to is on Sumner St. called AJ's Everything in that place seems to cost just $0.25 cents or on the corner of Bennington and Moore is Betty Anne's a place that still makes homemade donuts from scratch every moring called Sinkers jelly filled and covered in sugar.
Italian
Carmen's Kitchen
High quality Italian food. Small, cozy restaurant. Pretty good espresso depending on who makes it. Kind of expensive, but worth it. They used to have a small deli, but closed it - too bad. Next to Carmen's is an old school gentleman's cigar bar that is pretty cool.
Sub shops/pizza
Meridian Street Market
Always a lunch line out the door of cops, firefighters, construction workers, and local office workers. The Meridian St Special sandwich roasted red peppers, fresh mozzerella, basil, & chicken cutlet is excellent. Their Italian sub is very good. Nice to go dinners. Catering for parties is available and they have good prices for that.
Dough
The owners of this place are really nice guys and they make a pretty good pizza and good subs to. They pile rosciutto with capicola and genoa salami in their Italian, which makes it extra good. They also have hot pepper relish if you ask for it, which is not that common in Eastie. They have some interesting specials too they like to play around with creations involving buffalo sauce.
asian
There is a Vietnamese place on Meridian Street corner with Lexington or Trenton called Siagon Hut that makes excellent Pho and other typical dishes. I hear that it is well known among the Vietnamese community as being on par with the better known Pho places around town. Actually, Eastie used to be a large Vietnamese neighborhood and we still have the remnants of that through this restaurant and a Buddhist temple around the corner.

Colombian Tamale "hole in the wall" on Chelsea off Maverick Sq - Just found this place the other day. They make huge Colombian Tamales with 4 kinds of meat for $6. They look like something you would get on the streets of Bogota...pretty cool. Also have a guava flan type dessert thing that was awesome.
There is a Brazilian churascaria place on Chelsea between Maverick and Day Squares called Olievera's that is very good.
taquerias
Rosticeria Cancun in Maverick Sq Salvadoran/Mexican - The enjoyably chaotic atmosphere is the closest I have come to a classic Mexican taqueria - loud music, cramped environment, high energy and quick, decent food.
Taqueria Jalisco in Day Sq Mexican - One of the only Mexican owned and operated taquerias in Eastie. Their adobada and lengua tacos are superb.
