I tried this the other day, but it seems that nobody knows what a taco bar is. A really good one can be had at La Fiesta Grande locations in Pasadena and South Pas. They bring all the fixin's in individual bowls and refill as needed. I've found a couple of other places that do a buffet thing, which is kind of gross.
So, does anybody know of a nice all-you-can eat deal at a decent joint?
