Last I heard, Tres Hombres was still dishing up awesome beef nachos (during my undergrad days in C'dale they were $6.99 - kind steep for a poor college boy so I splurged only once in a while) and ice-cold Negro Modelo:

There is a Greek-owned place in Anna that I think is called the Village Garden. Solid, but not impressive, menu:

Boswell's Lounge is a tad east and a nice place to tip a few:

Southern BBQ was always good, but not great, BBQ. Pulled prok sammies with their own sauce on the side and good slaw.
