Amy and I took my folks to 1515 on Saturday night. We showed up at 6pm. The bar was empty. The upstairs - where the restaurant is - was about half full and dominated by a big party. The big party came in just before us so the service was a little erratic (pacing was off), but it was understandable.
The food was excellent. It was typical "fancy American cuisine", but fun flavors with great sides. I had a vegetable dish - always a good test of a chef - and he delivered nicely. The chocolate mousse dessert was outstanding.
So - food=very good. service=ok. However, at 8pm we were the last people in the restaurant. There appeared to be no second seating and - as we left - Amy commented that this feels like a place that won't last that much longer. If that's the case, it's too bad - the food is very good.
