Back in September I phoned the restaurant for clarification on DDPs. I was told for each credit, diners get their choice of 3 small plates, plus a choice of dessert and glass of wine.
For 2 diners (2 credits), they could select 1, either fish, chicken or steak platter, dessert and wine. On the deluxe plan, they could each add a small plate appetizer to the mix.
We never made it there unfortunately, but a number of posters here have had lovely experiences.
