You're not lacking for good food in Central Texas, that's for darn sure. My favorites are:
Chuy's Tex Mex (Barton Springs)
Kerby Lane, Gino's Pizzaria (Round Rock)
County Line BBQ (2222)
Chango's Tacos (Guadalupe St by UT)
Thundercloud subs
Freebirds burritos
Which Wich subs
Austin's pizza
Maggie Moo's ice cream
Crown & Anchor pub (San Jacinto)
I'm rarely limited to where I can eat in the area, not eating meat. When that happens, I stick with Ale.
