I went to Stack for dinner on a Saturday night, and the experience was a real mix of highs and lows. The ribs were really delicious and I enjoyed the cornbread, but the smoked chicken wing appetizer was disappointing and I've had better baked beans and brisket. The servers were all very friendly and attentive, but we were sitting in the corner and there were fruit flies flying around our table for the entire meal.... not a great addition. The atmosphere felt sort of like a Boston Pizza or Swiss Chalet, so maybe better for families and large groups than to impress a date.
I'd consider going back for the ribs (and a good selection of beer), but not in a big rush.
