There are not too many good authentic Chinese places in the Twin Cities. When China Jen opened early 2006 in Roseville we tried it pretty soon after they opened. In the North suburbs there are no Chinese restaurants worth going to within 10 miles. We were hesitant, but tried it anyway and were thoroughly surprised. The owner/chef had worked at one of the other authentic Chinese restaurants and opened China Jen with his wife and family.
Pros: Good authentic Chinese food
Cons: Small family restaurant so seating and service suffers when they are busy.
