I found an old thread from 2007 when I was searching for meal delivery services to provide a meal or meals for the family of a co-worker injured in an auto accident. There were no suggestions then, but this is 2012. All I could find were www.919dine.com/ which coordinates food delivery from Chili’s, Friday’s, Moe’s, Backyard Bistro, Carino’s, various Thai, Sushi and Indian restaurants in the Triangle.
I also found www.waiter.com/ which also coordinates delivery from local restaurants, but not an impressive selection of restaurants.
Then there's www.sendameal.com which ships frozen ready-to-heat meals, but I'm really looking for delivery of a hot, fresh meal from a local restaurant or caterer.
