Ka Chi just breaks in to the 4 star category for me. I've only had the hot stone bulgogi and spicy chicken bibimbap here and it's wonderful and very filling. However it looses 1.5 stars due to poor service which I admit is not something I found very surprising, but I could not justify a 5 star review without everything running well.
I must admit I've not had a lot of experience with Korean dining and I've never ventured in to Koreatown for food, so keep in mind that while I enjoyed Ka Chi, I might not know what constitutes good bibimbap/korean food.
The last time I was here, I also tried the the Korean Pancake, which was pizza like, and had some squid/cuttlefish pieces in it, while it was tasty it was a little weird for me to see a tentacle filled arm breaching the surface of my pancake. The pancake came in a minute before the bibimbap so I didn't really get to enjoy it properly. Highly suggest at least 2 hungry people to share one pancake appetizer which is large and not cheap.
The bibimbap came with a good assortment of side dishes that always satisfied, even the broccoli was OK.
We ordered soju to mix with beer (which wikipedia tells me is called somaek), and while it added something extra, more experimenting would be needed on my part to get a balance I would enjoy more.
The bill did come up for $55 for the 2 of us as the 2 beers and soju did add up.
I would definitely recomend Ka Chi if you're in the area and are not looking for chinese. Looking forward to broadening my picks next time I'm there.
