Cafe Koi is a very interesting place. It has a mood to it, so to speak. The vibe is laid back, lounge-like, and the lighting and music both make up a nice atmosphere.
The menu is quite expansive. Lost of appetizers, sandwiches, salads, and noodle/rice bowls. I ordered the Seoul Beef Noodle Bowl: chili-fire Shanghai noodles with grilled sirloin on top. It was fantastic. A couple of people with me had the Buddha Burger. It's a black bean and veggie burger which they seemed to really enjoy. I didn't have any of the house cocktails but they looked good too.
Apparently it turns into more of a lounge later at night, with live music and DJs. There's a small stage to the side of the eating area. I'd like to go back and check out some of the live music, and eat again too. Great spot.
