Casa Bonita was a childhood highlight of every Colorado trip. Waterfalls, cliff divers, fake gun fights, arcade, mariachi bands, exploring caves... I've had dreams about that place as an adult and I haven't been there in 30 years.
Food was abysmal...other than the Sopapillas which were great but you paid for the "atmosphere" .... which in the eyes of this then 8 year old, was five-star.
