First of all, Seoul Garden is a pretty authentic Korean restaurant. It is unlike most Korean restaurants that I have been to. Also, it's a place recommended by fellow Koreans. I like their side dishes which feature 5-6 different items from kimchi (cabbage, cubed radish, cucumber) to marinated bean sprout and dried tofu.
The place is a hole-in-the-wall and may be a turn off to some people. It also has a strong smell but that's not because of the building maintenance, it's the food that they cook. The owner barely speaks English and the service was so-so. The food was good and inexpensive though. A decent place for Korean food especially if you are looking for authenticity. Give bulgogi a try.
