They have over 40 loose-leaf teas to choose from - everything from Earl Grey and White Tea to Masala Chai and Tisanes (herbal/fruity/floral teas that are naturally caffeine-free). I really like the Earl Grey with Roses!
The blackberry and lemon scones were the best I've ever had! Served with devon cream and house-made preserves, they were light, fresh and buttery.
I love that there's three distinct rooms: the Purple Room, a French-style Lobby Tea Room and the Russian Red Tea Room. My personal fave is the Purple Room -- I like to sit by the fireplace.
Book a reservation before heading over for tea; they serve 700-1000 people a week and can get quite busy!
