Korean or Japanese Restaurant around Charlotte?
Sorry to be negative but as for Korean - don't waste your time. For a report on the now dismal state of Korean spots in Charlotte see the 9/20/06 edition of Creative Loafing (charlotte.creativeloafing.com). The dearth of this cuisine given Charlotte's size and demographic is bizarre.
Much better to do Vietnamese if that's an option. In particular, both Ben Thanh and Pho An Hua are very good. Both are located on Central in East Charlotte. Good luck.
