If you're looking for a special night out, I highly recommend The Corner House. It has a great country house atmosphere and is romantic and intimate. It's so nice to be able to hear the person you're with as well as eat a delicious meal.
The night I went, I was celebrating my anniversary with TM, so we went all out. We ordered crab cakes, lobster bisque, duck and lamb entrees and a fantastic cheese plate and macarons for dessert. Everything was delicious and the presentation was too notch. I've posted pictures if you're interested, but be warned that you will be susceptible to severe mouth watering.
What I liked best was the attention to detail. The staff were attentive, and when I mentioned on my Open Table reservation that we were celebrating, they were sure to add a special touch to our dessert plate. Can't wait until I go back!
