I've been a loyal customer for probably most of my life to this restaurant ever since i was little ! I live pretty close by so i go their often for lunch when i'm to lazy to cook for myself or i go when my family wants to go as well.
I suggest going with a group but going with a group or family around peak hours (lunch and dinner) as it may feel a little awkward eating alone but out side of that its pretty quiet there.
I really enjoy the service as the waitresses are very friendly, food portions are pretty huge and tastes great. prices seem pretty fair and if you bring friends to split the bills on side dishes its even better!
My favourite thing to get is the Jajang myun (black bean noodles) tang soo yuuk (sweet and salty sauce on deep fried pork strips) split bowls. they have combo deals with sides and main dishes for groups and stuff also so i suggest that when you in groups! They also do take out so you can bring the food home and eat it!
On weekends it gets pretty backed so i suggest you make reservations if possible also, so if you plan on eating and want it to be quiet i suggest you avoid weekends and just order takeout!
