Boskone will be updating the Restaurant Guide for 2011. But, to help you with your planning, here's a link to the 2009 Restaurant Guide.
Restaurants That Deliver Food...or You!
My Diner in South Boston has free delivery (Mon-Sat 5am-2pm, Sun 6am-2pm) so you can have breakfast or lunch delivered!
J Pace and Son has opened on 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.
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. I hear there is also Chicken & Waffle open late on Mass Ave.
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.
