I've been here multiple times over the years including during trips back home after living in korea. The family comes from Busan and this is evidenced in the cooking style - completely authentic completely Korean. The food here is exactly what you will get if you stop by a small family restaurant in sacheon, jinju, changwon, busan, gimhae, etc... Do not ever come here and expect the 'waiting on me hand and foot' experience of other restaurants in the USA. This is as real as it gets folks and service isn't the priority in Korea - food is, which, I am delighted to say theirs is simply superb. THIS is where I go if I want food from gyeongsangnamdo, my home province.
Banchan - freshly made with homemade perfectly fermented kimchi, perfectly cooked soybean sprouts.
Dishes - try the kimchibokumbap, definitely take a stab at the bulgogi (you won't find better fresher bulgogi anywhere unless you just bought a kilo in a TopMart in Korea proper). Their dolsotbibimbap reminds me of Jinju but am sad they don't have plain dolsotbap (usually you scoop the rice out and eat it with banchan while putting water in the dolsot to make a rice soup). Kimchijiggae(stew) is fantastic here.
Whatcha waitin for? It's not like a gimbapcheonguk is opening anytime soon lol.
