I grew up in the Denver area of Colorado and one of my favorite restaurants was Casa Bonita in Denver. Not at all for the food because it is terrible, but because of the atmosphere and fun activities. The inside of the restaurant is like a Mexican rain forest, and for entertainment they have cliff divers who perform as you eat your meal. There are also Mariachis who perform and other entertainment. They have a courtyard area where they do pinatas and a cave that goes behind the waterfall that is filled with scary things.
Casa Bonita was featured in an episode of Comedy Central show South Park. In the episode Kyle gets to have his birthday party at Casa Bonita and does not invite Cartman who then schemes and figures out how to take Butters' spot at the party.
A few years ago Dustin and I decided to go to take Austin while we were visiting my Mom and Sister in Colorado. Dustin was interested in it after seeing the South Park episode. I was pregnant with Katy at the time and got the worst heart burn after eating their food, but it was fun to take Austin and see his reactions to a place that I loved as a kid.
