First Floor and Mezzanine


About This Venue

Within the First Floor and Mezzanine levels lies an oceanic wonderland seating 100 people. Mermaids and sea creatures swirl around the mosaic floors and columns. The cloud-like ceiling creates a dreamy atmosphere. A triple level tree stage and dance floor area are perfect for a band, presentation or champagne toast! Native Missouri fish and turtles swim in the 5,000-gallon aquarium ornamented with oyster shells, found sea glass and mosaic tiles.

Above the first-floor mosaics and aquarium, the mezzanine level overlooks the colorful space and includes many more exciting nooks and crannies to explore.

Venue capacity is 100 seated, 200 standing.
