i would avoid Iron works, I never understood why folks told me I HAD to eat there. If you are looking to drive about 20 -30 extra miles, check out Billy’s in Bastrop. Its on the highway to Houston. (Michael Stern did a review of Cartwrights, which is just down the street.) While i have never been to Cartwrights, i can’t imagine its better than Billy’s.
avoid Stubb’s unless you are there waiting for a band to play.
