CASH ONLY.
Didn't like the place. The service is either rude or friendly depending on your server. The food costs too much for mediocre quality; the real Rose Tea Cafe in Squirrel Hill is much better.
I had the marinated pork over rice; it is essentially chopped pork, rice, and a boiled egg. The meal was far too salty and I didn't like it very much.
The server recommended the Taro bubble tea, which was "very very popular." They are supposed to have a rich, creamy texture but the one I had was very watery and not sweet. I'll regard this as a anomaly, but overall the experience wasn't worth the cost.
