The Cave is the nation’s only restaurant located in (you guessed it) a cave, serving American steakhouse/seafood and Italian fare. The space may not get much natural light, but it has waterfalls, fish ponds, and even a view of the Gasconade River.
The space began as a natural cave that served as a dance hall in the 1920s, situated three stories up on a limestone bluff at a campground (visitors can still rent the cabins). Back then it was not spacious enough for 225 to dine, as it is today; the rest was carved and blasted out over the course of four years.
