I regularly visit Dean & Deluca with friends for wine and sushi and I must say it's never let us down so far. You can find good wine at a reasonable price and the same goes for sushi.
I have yet to branch out and try their hot/cold food but I hear very good things. Their coffee/espresso bar hits the spot and they have soymilk! Score!
The place is clean and the staff is very helpful.
The one and ONLY complaint I have (and the reason there are only four stars instead of five) is the uncovered pastry counter. I will never eat a pastry at Dean & Deluca until they start putting them behind a glass case. Seems way too unsanitary for me. And flies always seem to find a way in to places like this. Please - D&D, if you're reading this, cover those cupcakes!!
