Beautiful building! You might strain your neck looking up at the ornately carved ceiling. We had high tea there a couple years ago for mother's day, and it was wonderful- even my brother enjoyed himself, so this is not just a tea for girls! They're tea selection is great, my fave is the Blue Moon tea.
We go out of our way to go to In-tea. They have tons of loose teas and knowledgeable staff. You have to pay for re-infusions beforehand, so don't forget if you are planning on sitting for a while sipping tea. We usually each get a cup of tea and then a few loose teas to take home because they are reasonably priced. They have tea cocktails, cold tea based drinks, and even tea slushies (like and Icee machine with a tea-based drink). It's a nice place to sit and chat, a small establisment but in summer they have a few tables outside as well. a very casual atmosphere. As for food, they have nice pastries (I like the meringue cookies), and some other offerings but I haven't personally eaten much there.
