I've been a regular of this place ever since they first opened, and they've consistently been one of my favorite restaurants in the Valley. The waitstaff tend to be pretty hospitable, the food is delicious, and the inclusion of boba drinks on their menu in the last year or so definitely makes this place worth visiting again and again.
A word to the wise, however - while the food here is extremely delicious, the the taste and preparation may vary greatly depending on the chef on duty. So, yes, while the food is good nine out of ten times, just prepare yourself for the occasional dud. Also, if you've never had Korean food before, be prepared to pay a little more than you normally would at an Applebee's or a Chinese restaurant - you will certainly get your money's worth, but be prepared all the same.
