Took my mother here for a belated birthday celebration and it was lovely! Tasty and attractive food, voluminous tea selection, prompt and friendly service, comfortable and classy furnishings. I particularly liked the 'endless pot per customer' policy, as it allowed us to choose teas without having to argue over which to share. Located in the middle of downtown Frederick, so a trip to Serenity could be incorporated into an afternoon of strolling and shopping. Retail shop in the back to purchase loose leaf teas, scones, fine china, etc.
