Everyone @ UTMB knows this place because it's right outside the front door next to Shriner's. Tourists need to know about it as well. It's cheap, quick and tasty. They serve up great american staples like meatloaf and chicken fried steak with fresh sides -- all at a cheap price (<$6). Only downside is the hours, so don't try to go there outside of the lunch period because you'll be disappointed.
Bottom Line: Great lunch spot: food cannot be beat for the price.
