Corner of 17-92 & 436
all damned night!
This place might look like a dump and most of the staff doesn't even talk English, but there's no better place to go to get your nutrition on 24 hours a day.
Beto's serves a variety of authentic Mexican food cooked in front of you on a griddle. They have also have a breakfast menu served 24 hours a day. If you're looking for fast, dirt cheap food and health isn't a high priority on your list, Beto's will become a regular stop.
Recommended: the chicken chimichonga. Nothing like a deep fried burrito to get you going at 4a.m.....
