Note: The Boston Wine Expo will be taking place in the nearby Seaport Hotel. Even if you have no interest in wine, this could make it harder to get reservations for dinner in the Seaport area Saturday and Sunday night when several thousand wine enthusiasts will be in the area, looking for dinner. Consider making your reservations early. Additionally, the Boat Show will be in the adjacent convention center, so the Seaport area will be very busy on Saturday and Sunday.

There is a small grocery/deli nearby - J Pace and Son at the corner of Pace St & Northern Ave. This Italian market has a grocery store and a take out area including hot prepared foods, full bakery and salad bar. They also do catering if you wanted to share with a group of friends.

Lee Chens has both Chinese and Mexican dishes. Beans are cooked without animal products. Tel: (617) 269-0061
KO Catering and Pies, 87 A Street, is takeaway food (a few tables) but if there are any homesick Aussies in the crowd, it might be worth to stop off early to pickup some meat pies or other Australian favorites. They also deliver several nights a week.
Amrheins Restaurant in South Boston has a new free shuttle service. For a free ride both ways (Mon-Sat starting at 5pm and starting at Sundays at 10am) you would need to make arrangements with the restaurant.
Yes, Boston does have a 24hr diner. (Well at least on the weekends...) So if have a car or cab and need late nite food, you can drive to Victoria's Diner at 1024 Mass Ave. I hear there is also Chicken & Waffle open late on Mass Ave.
