Fitting that this should be my first post, but I order delivery more than I should and I live in Logan Circle. So here's a list in no particular order:
1. Chinese: Virtually always Great wall. I only really ever order the ma la (the rest is so so at best) and my record time from phone hang up to knock on the door is 9 minutes.
2.Pizza: I alternate between Baffetto and Duccini's. Both are very good options but totally different.
3. Thai: I'd order regent if I could, but I'm a block outside the delivery radius. I usually go with thai tanic (alright) or sometimes simply home (better, but more expensive). Have yet to try thai x-ing, but looking forward to it.
4. Wings: Wingos is very good. I used to order from wings over washington, but it's far and I think wingos is better.
Hope this helps.
