Hidden gem! They use MSG in almost all of their food though, so consider yourself warned.
Get the beef Bulgogi. It's their specialty and it's flippin delicious. I lived down the street from this place for 3 years and never went in because it does indeed look a bit sketchy from outside. It's a very different experience, and pretty cheap
When we were there it was cash only. I'm not sure if that's regular or if their machine was just on the fritz. Anyway, it was delicious.
