David's Tea always has a friendly staff who have tried their own wares. Walk in to sample one of their two different daily blends of tea and have a sniff from the canisters of their multiple blends of leaves. They stock White, Black, Green, Oolong, Pu'erh, Rooibos as well as exotic combinations and their own creations. There is a wall of gift ideas such as tea kits, teapots, books and cups (check out their travel mug/tea press with hidden compartment to store tea).
Prices are reasonable and I bought some tasty Earl Grey and high grade Matcha. Don't forget, when you buy 100 grams of tea, you also get an aluminum tin to store it in. Bring it back in when you finish all of your tea and you get a slight discount off your next purchase.
