Don't be fooled by the theme and the drunk college kids hanging out in the restaurant, this place has solid sandwiches. If you want something cheap take-outy but better than say, Subway (and I LIKE subway!), Cheba Hut is a good choice. Just make sure you're comfortable ordering a "blunt", etc, because the menu items are all pot themed..
I'm not a vegetarian but the Griefo, one of the meatless choices on the menu, is always very satisfying. My favorite part is the jalapeƱo cream cheese! You should add it to whatever sandwich you end up getting :)
Never ordered delivery but they do have a pretty snazzy delivery mobile.
