My other Korean sushi buffet place is Gah Rham in Beltsville. They're both similar and worth doing, but I appreciated the Kimko spread better. I think I was the only non-Korean there but they seemed to take a little better care of me. I was asked several times if everything was ok or if I needed anything. My main server was raised in HoCo.
Korean sushi buffets seem to follow the same layout. The previous Korean Howchow post did a good job of explaining the Korean food part of the kimko buffet. But how do you eat fried rice with chopsticks? This is not the kind of place you ask for a fork, though I'm pretty sure they would of given me one. This day's buffet was light on noodle dishes. The only one was a salad noodle combo that was very good. The spicy food was not very spicy except for the killer raw green hot pepper half in one of the dishes.
The sushi component consisted of four different trays of raw fish on rice at the top level and over a dozen and a half sliced rolls on shelves below. There were vegetarian, raw fish, and cooked fish rolls. Several were in the fancy category with or without a tempura component. They were all labeled, but the fancy rolls were just labeled special. You have to guess at the contents. You use tongs supplied in a container at the beginning to select individual slices. The variety is overwhelming. It's fun to watch how many slices a person can stack on one plate. Personally I go lighter on the sushi (one layer not touching) and heavy on Korean food (it can touch). This isn't Sushi King or Sushi Sono, but it's decent.
I'm not a good person to judge quality. I don't even know the names of this stuff but I did like everything. The Korean food was not labeled. I'll go back again and I'll keep recommending the buffet.
Kimko's buffet is $11.95 and runs 11-3 weekdays. Kimko's is on Rte 40 at Bethany Lane. It used to be called Bethany Seafood.
