I've gone here many times! You definitely have to have a reservation and it's almost impossible to get a table for one person, that being said I always leave happy. They have a great verity of teas, a lot of different portion sizes for foods (I highly recommend the scones) and their lemon curd is one of my favorite things on this planet. If you need a place for a baby shower, bridal shower, of just an afternoon of relaxation I would 100% recommend this spot.
My mother-in-law and I walked in, no reservation and were seated immediately. The room was really cute and the service was wonderful. We had a really nice time! I wish there were more gluten-free options on the menu that were snack-sized but that is not a big deal because everything else was so great that it's a blip on the radar.
