It's more like a 3.5 but I'll round it up to a 4.
Their set meals(and they have a few you can pick from) are really awesome. We had 10-11 people and they gave a huge portion that was able to fill us up with only $20-22? each. THe reason why it's more like a 3.5 is because the quality meat is only okay. It really could be better but of course it's still better than your typical AYCE bbq. I actually think the meal went from great to good. Their appetizers( the little small dishes that korean places serve were great and we got soup, bibimbap(which I thought was really good and flavorful). They also had their happy hour from like 9-close? or something like that but i have to say the meat(pork belly + beef toro) weren't great all even though it was the happy hour price.
Regardless, I think for a bbq place like this, they give you a great portion for a good price is the reason why I gave it a 4. It's not the best non-AYCE place but their set meals are nice and worth it.
