This is another case where 3.5 stars would be ideal.
The concept is cool..it's a restaurant that focuses on employment and career development for the deaf.
I would call it more of a tourist destination than a foodie one.
It's roomy and clean and the staff are friendly and courteous. A pint of cracked canoe (which you sign by making a zigzag with your finger followed by the motion of paddling a canoe) is a steep $9. The food is average. The chicken piri-piri was a pricey $28. I also tried the soup of the for a reasonable $5 and a nutella tiramisu for $9.
It's worth a try for a unique and humbling experience but won't rock your tastebuds.
