If you are ever in Fort Worth go to Tommy's. It is near the NAS-JRB on 820 west of Lake Worth (the actual lake not neccesarily the town) I think.... Man it has been forever... But it is off of 820. The place is inside of a gas station... yes I said gas station... They have a burger there that has EVERYTHING on it. They call it the Junkyard Dog. Get that, and know that it really doesn't get any better than that.
As for Austin and burgers I have been a little dissapointed.
Hey Kosher, what do you say for a good burger in Austin?
