The 'K' is what has been known to go down for dry cleaners and nail salons. Don't act like you know more about Koreans than me. I'm a fucking Korean. You're fucking white. Those cheap, low-startup-cost urban-area businesses have nothing to with what were talking about here. Authentic korean restaurants. All the good authentic Korean restaurants that open up here, have done so after already opening 1 or 2 restaurants in Korea and Europe and achieving acclaim and significant financial assets.
For the kiddies here who scoffed at 500k, try opening a authentic ethnic food restaurant with less than 500k in the D.C. Metro area. See what kind of restaurant you end up with. You even been inside Woo Lae Oak?? They put at least 3+ mil in that place. Dumbass. Go back to playing XBOX.
