I found this place quite easily after following the directions in Bob Sultan's review. And it turned out to be a lot like how that review described it (good reviewer!).
I went on a Sunday evening, and it was quite quiet, mostly small groups of women dining and chatting. It is bright, and smells of joss sticks like a lot of the places in this area. There is a little Buddhist shrine and a TV playing what seems to be the Buddhist equivalent of 'Songs of Praise'.
The waiter showed me to a table, he's very smiley and welcoming. He's speaks a little English, and wants to, as well! First he shows me a notebook with their selection of teas, I pick Oolong. He then showed me the two menus, exactly how Bob describes, English with no pictures, Chinese with pictures. He stands over me as I look, which is a bit strange but I'm OK with it, and after about 30 seconds he recommends a dish of mixed mushrooms, that flat tofu stuff I've become accustomed to while here, carrots and celery, which I order with some rice. Total price 34 RMB. It was quite tasty, nothing special, like a lot of the food in this city, but it was a large portion and after eating it all I felt satisfyingly full without feeling bloated.
I ordered more tea, and sat for a while, because this really was a nice place to be in a bustling city. Like I said, I was made to feel very welcome, and the waiter even had a little chat with me about where I'm from and what I'm doing, asking if I'm vegetarian, explaining that he is too, and he's Buddhist. I'm here for three months, and I think I'll be back to sample more of the menu.
