Update: I've been to Franchia a couple of times and here's my general summary---it's a place with great decor and friendly service, but the prices are high on everything and the food isn't particularly inspiring.
I didn't try any entrees, but the dumplings were decent (if a bit bland) and the tofu cheesecake was tasty, but not the best I've ever had (it was a little dry). Their chocolate pudding was tasty, but nothing different than what you could get at Whole Foods for a couple of bucks in a plastic cup. They were out of every other vegan dessert the second time I went there, which was disappointing (I've heard good things about the coconut blueberry cake).
Franchia has an extensive and impressive tea selection but they charge sky-high prices. For a cup of any of their specialty teas, you're going to set yourself back $4 or so, which is ridiculous. To make matters worse, they don't offer pots of tea, so you can't share with friends, or maximize your value by getting a larger amount of tea upfront, and a decent second steep later.
So, this is a nicely decorated, quiet place to meet for tea and snacks, but it's on the pricey side.
