I came here recently as I had a groupon for $86 for two (includes an appetizer, entree, dessert and a drink up to $8 worth). The experience was incredibly unique and interesting. There are cheat sheets on the table so don't worry if you don't know ASL. TBH you only really use ASL to order the food. The service was impeccable - our server was extremely patient and made us feel very welcome!
Unfortunately, the food was mediocre at best. We ordered the Caesar salad for appetizers and it was overly soaked in dressing. I ordered the steak medium rare which came with french fries and vegetables. The french fries were soft and not crispy at all, whereas the vegetables were plain and lacked flavour. The steak was however delicious and cooked to perfection. My date ordered the Mahi Mahi fish which also lacked flavour. For dessert we ordered the triple chocolate mousse which was positively delicious. Unfortunately, the groupon only offers a limited number of the items on the menu so beware of that if you're looking for the groupon! The bill came out to be about $126 with tip and taxes which IMO is overpriced for mediocre food. Overall though, we had a lovely time and would recommend this place not for the food but the experience.
