I ate there a few years ago and thought everything was delicious and creative. It's a nice switch to have so many vegan and vegetarian options. The huge selection of teas are a lot of fun, too. They are certainly still open, as I've passed by recently without stopping in. Sadly, the front awning and entrance way looked a little worn out, giving the impression that the restaurant is past its prime. I think it's still a popular neighborhood spot, though. So, without having tried it lately, I say you should definitely go if you've been looking forward to it. The tea sandwiches were delicious! I believe it's cash only.
On a related note, the Teany iced teas have been in our local markets for sale for years, now, so the business as a whole seems to be relatively successful.
