In general, most Champaign area Korean restaurants start out with bad service. This place is no different. After ordering your food, it typically takes 10-15 minutes to get your food, and it doesn't always come out in the same order as you ordered. On top of that, you'll often have other people that cut into line and get the same food that you ordered before they did.
On this occasion, I ordered duk mandu guk and it came with soggy seaweed in it. For the price of $10, it was a bit more expensive than other Korean restaurants in the area. In addition, it didn't taste spectacular to any degree. The only consolation was that it came in such a big bowl that I could take a little bit home for a leftover meal.
Another dish that is pretty popular is their BBQ bulgogi. It usually comes with a special sauce but it really depends on the day to figure out whether it's good or not. Sometimes, it's under cooked. Other times, it's over cooked and burnt. They also use about a 50% onion to 50% meat ratio so it seems like you are paying for a lot of onions and not a whole lot of meat.
The seating is usually crammed so during rush hours, it's hard to find a seat. There is very little room to back your seat out as seats are pretty much back to back.
