Gengis Khan Buffet offers a wide variety of sushi and seafood for lunch and dinner. The food is fresh and plentiful. The sushi is exceptionally good and for the price of a lunch buffet, $7.50, you could make a meal just of sushi. They do have chow fun, chow mein, rice dishes, fresh seafood like clams and lobster (sometimes) as well as traditional stir fry dishes. The atmosphere is OK.
They do request that people not take more than they can eat, due to problems with waste at buffets!
