It's a cozy place. The servers are always nice for the times I've been there.
I've had a few of their drinks - given the great number of choices, I didn't expect all to be good: the slushes tasted a bit too sweet. I really like their rose milk tea though (looks awesome in the to-go cups).
I don't have high expectations for food at such a small tea place, so I don't generally order them. I've only had the green-tea-flavored thick toast (which was decent) and the cheesecake platter. The cheesecakes are like the squared little ones you can get from Costco, which means they taste okay but nothing special.
In general I'd recommend it if you are looking for a place to chat or study (it's usually quiet and the lighting is pretty good/not so dark as Go-for-Tea's, so I suppose it's actually a nice place for studying).
