On FoodSpotting this place is a duplicate (with far better photos) Mosaic At Lambert St Louis International Airport. As far as a review... Everyone hates their job and you'll taste it.
Service is slow but server was attentive. They are out of half of their menu options. They should consider reworking their menu so they do not scam customers with a fake menu.
Horrible service and food. Waiter was nice enough but hostess was horrible and kept scratching her head. Burger was dry with no flavor. Not eating my lunch. Ick.
