My friend and her husband and I went there on Friday, September 29. I was visiting from out of town so it was my first time there. Of course, it was very busy because it was a Friday night, so there was a 40-minute wait for a table. We went to the bar area while we were waiting, which was very small and packed with people, so there wasn't much room to stand. Mixed drinks were $7.95 each, which I think is kind of expensive, but my drink tasted great and the bartender was very nice.
Once we were seated at our table, we had a great waitress. The bread they bring out to your table is wonderful, and it came with strawberry butter, which was excellent. I ordered the potato-crusted rockfish and garlic mashed potatoes, which were excellent as well.
Overall, the service, food, and ambiance were great. My only complaints were the small bar area and expensive drinks. However, I highly recommend the Mill Street Grill. If you go on a weekend evening though, be prepared to wait awhile for a table.
