Very traditional savory menu, scones were good, and the pastry selections were excellent. The house blend tea is very, very good – an Indian black tea with babaco fruit (kiwi, pineapple and one other kind of fruit taste). The staff is marvelous and the server I had was knowledgeable about teas. The live harp music was wonderful. The tea room itself is small and in a side lobby but despite being open to the larger lobby it still seemed quiet and set apart.
The price seemed reasonable for DC. The price of 3 ounces of their house blend tea, however is definitely high. I bought some because I want to share it with friends, but I will have to think about buying any more, despite the fact that I really, really like it.
Reservations are required, though when I arrived early, Julie, the hostess, sat me immediately.
