I can't speak for the dining room- but we went in here and sat at the bar the weekend before Valentine's Day and I was super impressed by the friendliness and efficiency of the bartenders considering they were CRAZY BUSY. Like 3 people deep, crowds around the bar, and constant tickets printing for drinks in the dining room busy.
The wine list is ludicrously expensive, but the food and drinks are always on point at Maestro's concepts. Just go in expecting to spend over $100... for yourself. ;-)
