Part of the Alinea group of restaurants, The St. Clair Supper Club is below Roister, next to The Office. You walk in and immediately feel like you are in the 80s. Great playlist, high cushioned bar, lights on chains, fake wood wall panels… The menu is limited, the food is fantastic.
Make sure to go hungry because a) portions are large and 2) dessert is excellent.
Get the chef counter if you can and, if you do, talk with the chefs – always makes for a more enjoyable dinner.
