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. This is about 1.25 miles from the hotel.
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.
