Extremely authentic. The Shanghai baby bok choi tasted just like the bok choi I ate in Shanghai. The also have a good steamed fish and one should not pass up the cold chicken. I can't stand most Chinese restaurants as they all have sweet sauce and too many vegetables for my liking. However, I'll go to Ka Mei 6 days a week as they have a large menu and the food is the most authentic Chinese in Pittsburgh and their prices are reasonable too.
