I have been here many times, both to the (better) subterranean location as well as the new two story location. While the food isn't the best and the beer is just plain horrible, it is very cheap and everyone in your party can usually all find something they'll eat on the simple menu.
I give it one star for corralling the obnoxious Americans in one place, keeping them out of better spots and one star for still serving beer out of 144 oz pitchers. You don't see them everywhere.
If you must visit this tourist trap, the trick to this place is to go while it is still light outside before the trash starts rolling in.
