This isn't the Queen Mum's tea! The atmosphere is very Asian and fun. The food is wonderful -- I had the curry chicken for lunch on my first visit, and the almond cookies on the second. They have a very wide variety of loose leaf teas, with a cute little pot for hot water. Service is pretty good, except for when it gets really crowded in there, but that's just way to sit back and relax.
I absolutely love this place! They don't have a wide selection of teas to choose from (only about 5, whole leaf to my knowledge -- only one is decaf and that's what I drink -- but they have their own special blend), but it's worth the trip to Aldie, VA. The atmosphere is quaint, the tea service is absolutely charming. Definitely make reservations before heading out there though. The place is small and intimate, so make sure you have a table.
