I had phoned the restaurant and was told that 1 TS would give you a choice of 2 small plates, a drink (I believe wine was capped at $16.00) and dessert. On deluxe you got a choice of 3 small plates, wine & dessert.
If you wanted one of the entrees (steak, chicken or bass), it was 2 credits (1 each for 2 diners) and that included a small plate each (deluxe), wine or other beverage and dessert.
