Did you go in the late 80's/early 90's? We used to go to the one by the house off of 59 on the other side of Westwood Mall, and it was amazing. Went again early 2000's and the quality had gone way down. Drove by the other day and now it's a Zorro's buffet, but don't know what they're serving. Chacho's is alright, but it's more of an after hours "grub on shit while you're hammered" joint.
If that's what you're into go to La taqueria tapatia. Stay away from Rucchi's. Also, went to a Country Kitchen Buffet once and got sick as a dog so never went back. There used to be a joint called Ryans that was just like GC, but don't know if they're still around. And, when you're really trying to go apeshit there's always CiCi's.
