Before going to the zoo,
heike, Karl, and I went to Zoe's Herbs & Teas (FB page
here) in the West End (42 Wabash St, Pittsburgh.) It is a new tea house (with more than just tea) run by some friends of ours. I highly recommend going and checking it out. They have a lot of loose teas and various styles of appropriate snacks, as well as numerous items that would appeal to people who like good teas.
The zoo visit was great. We all had a fine time and the weather stayed warm enough that walking around with Karl was no problem. Pictures from the visit are stuck
here.
