Burritos/Tacos/Quesadillas: Matador (local).
Burgers and fries: Five Guys or In 'n Out. I miss Jack in the Box but there is only one around and it is an hour away.
Pizza: Anywhere local. We have 10-12 local pizzerias that are absolutely delicious so whichever has the better deal at the time gets the money.
Sandwiches: Cheba Hut. Or Silvermine. Cheba is superior, but their hours are wonky and they usually don't deliver where I am. Silvermine is nowhere near as good but they are open until 3am every day and deliver everywhere in the city.
