Reservations may not be a bad idea. The is a unique dining experience. The restaurant is located in a cave in a Gasconade river bluff. From the parking lot you are driven to the cave and lifted in an elevator to the entrance. The interior is very nice.
Food is good and the experience is unusual.
Located off I-44 west of here. The drive will take 45 mins to an hour. Reservations, again, a good idea. Generally opens again in early March. This place does not take credit cards OR checks.
