This is more of a 4.5 star than a 4 star review.
Sura has a delicious variety of Korean cuisine. The only thing that I could live without is the cheezy "Asian foods" that you can find to the right of all the Korean barbeque. However, the meat here is exceptionally good especially for a buffet. I don't see how you can ever be upset with all you can eat Julmurook, Kalbi, (Dwaeji) Bulgogi. I just don't see how...
Service here is also great. It probably deserves a solid 4 stars. This is because you will usually get excellent service the first 10 minutes of your meal, and after that you may have to get the waiters attention if you need anything else. However, they will always serve you with a smile and never hesitate to change the grill for you.
I do prefer this place over Woo Che because the food quality and variety is better here, and I do believe that it is worth forking over the extra couple of dollars for a better overall experience. However, do not let my review deter you from trying Woo Che as well. Both are excellent restaurants to dine at!
