Taco Talk in Obie's is good as well as the Exxon on Pinehaven. I am a big fan of Chick Fil A myself. $5 for a chicken biscuit, hashbrowns, and a drink.
Here is one that I would not seeing all day long on this wall, but also something I would highly recommend. Cafe Nine and the Cobalt Rhythm Kings. Awesome open mike...
