Okay, after searching far and wide the land of las vegas for some legit KBBQ I finally found one that I deem up to par with Socal standards (minus rice cake). Its just.. it's pretty pricey if you get the everything combo, which has the good stuff i like. And the service wasnt so great because they were understaffed. 1 stressed waitress: ~7 full tables at a ayce bbq just doesn't work well.
In terms of the food, probably this place and magal are the places I would recommend for kbbq in vegas. I enjoyed their marinated kalbi and naengmyun (not included in ayce)
