How is the dim sum selection, and quality?

I doubt they have that there

Dim sum is a variety of different dumping dishes, usually served in round bamboo containers. In a non buffet restaurant, there might be a dim sum cart that gets pushed table to table. Steamed, boiled, and fried dumpings as well as different rice noodle dishes can fall into the dim sum category.

Not really sure what dim sum is or if they even have it there never had it

I don't recall seeing dim sum when I was there.
