A west Denver landmark, Casa Bonita is more of a theme park than a restaurant. A pink Spanish cathedral-type bell tower greets visitors, who discover nonstop action inside: divers plummeting into a pool below a 30-foot waterfall, puppet shows, a video arcade, "Black Bart's Cave," and strolling mariachi bands. The cafeteria-style service is quite an undertaking for a restaurant that seats 1,100! There's standard Mexican fare--enchiladas, tacos, and fajitas--along with country-fried steak and fried chicken dinners. While the food is average at best, many plates are all-you-can eat, and patrons need only raise a miniature flag to get another round of tacos. Meals include hot sopaipillas (deep-fried sweet dough), served with honey.
