I live near a couple military bases. There's a Korean restaurant in the area, and over half of their clientele is military, formerly stationed in Korea. They want authentic Korean, just like when they were stationed there, and they get it. Which is why they keep coming back over and over.

If you go to Hawaii, and can get somewhere near a military base, I'd imagine you'd get enough southerners that are stationed there, to come in and support the place. Then you'd build up from people that have never had it, and like it.

We have quite a few northerners that have migrated, or stationed here. I've even met quite a few that had never had sweet tea, and they drink it by the gallons now.

Good luck!
