I love, love, love Vincenzo's. It is located in a neat old building downtown that is just as classy inside as it is outside. The prices are high--the last time we were there, my husband and I spent $125 for the two of us, including wine and dessert--but the food makes it worth it. Food quality and presentation are both superb.
As a side note, this is where we had our rehearsal dinner for our wedding. They put the 20+ people in our party in a very well-appointed room and helped my mother-in-law plan the menu, arrange for flowers for the table, etc. They allowed us to have a small string ensemble playing in the room before dinner and while we ate. The woman who was in charge of special events was apparently a little flaky, and there was construction going on upstairs, which caused some confusion, but the actual event went off perfectly and everyone LOVED their food.
