Dallas Korean food

Can't help you for near downtown, but for some reason this strip center in far north Dallas in Carrollton and the area around it has the largest gathering of Korean restaurants, bakeries and groceries. I take clients here all the time. Worth the drive from downtown.

There’s a ton. For kbbq go to Ari. That area should be loaded with a bunch of korean places. For authentic we like to go to Hansen Pocha or Ddongo. Both very good

You can try here, might be a little hard to get a reservations as it is Valentine's Day.

There are several around this area. Another good one is Korea House just down the street.
