Grace is quite possibly one of my favorite local restaurants! I've been three times, and I've found the wait staff to be friendly, and knowledgeable; the décor to be clean and romantic; and the food to be delicious and in-season.
The menu varies with each season, so it's easy to visit more then once. The portions can be on the smaller side, so be sure to ask the waiter if you're concerned.
I highly recommend making a reservation, as the restaurant does fill-up fast. If it's warm out, ask to be seated in their courtyard; if it's winter, ask to be seated by their corner window! Great place to impress a loved one- Ryan Gosling and Rachel McAdams were seen canoodling here last Summer, pre-breakup.
If you're a big group, reserve their upstairs room- it's perfect for an intimate group dinner.
