take your pic....Big Nates BBQ, Zante Pizza, you can order to go but not delivery from Little Nepal, if you want a broader selection, join waiters on wheels and you can order from a plethora of restaurants around the city that don't even offer takeout/delivery themselves.
www.waitersonwheels.com if you want ethnic there is always take out from Cafe Ethopia on Valencia btwn 19th & 20th. Dusit Thai & Pad Thai on Mission btwn 29th & Coolridge deliver and have excellent menus. I've lived here my entire life and there is no one single place worthy of all my business as there are just too many good places to narrow my field that much. but if you want all cuisine i'd go with waiters on wheels for their selection of restaurants, they have a couple of good vegitarian / vegan listings. Good luck & enjoy!!!

for japanese there's SuperstarYoungDe (they are located across the Glen Park BART), & they have chinese, too.
there's also Ankor Borei (Cambodian) & they are GOOD :o) located on Mission bxn 30th & 29th
I often have ordered from Jasmine Tea House, which is yummy & kind of different Chinese food
as mentioned before, Spicy Bite is very yummy!
bon apetit!

i like zante's and jasmine tea house.
