We had a mixed experience at the Cafe (downstairs). We do love the Express.
The place was crowded...the tables were jammed so close together that DH and I had a third person at our table: the back fat of the guy at the next table. I am not joking.
DH had the sushi special and said it was perfection...it also looked beautiful and the price was fair. My appetizer (pot stickers, I think) was wonderful. However, they destroyed my Chinois Chicken Salad by drowning it in dressing. They do it better at the Express (same big portion, lower price).
Our drinks were not well made...expensive, overly sweet, no discernable alcholol.
Definitely worth trying for certain menu items.
