I go to Mei regularly. Last time it was so full of people, and there was only one waitress. Serving table and collecting bills were all on her. No wonder everyone complains about the service.
We were so thirsty after finished the dishes. We would like to fetch ourselves some water to drink because the waitress was so busy. We only found all the water bottle were empty, and had to bother her for some water. We felt sorry for her also when the chef/owner (maybe) was not nice to her.
The food is genuine Chinese food for sure. The taste is wonderful. Go for the Chinses pancake/crepe, fried pan-stickers. tofu dishes. You will love them. The BBQ is only OK compared to other dishes.
