Manna BBQ is the best Korean bbq in AZ. You don't need to read anymore, just go eat here.
Alright, if you're still reading, Manna's got the best quality meat--you can see how marbled the meat is in their cuts, and you can definitely taste the flavor. If they only had beef belly and brisket I'd be completely fine--that's how good it is. Their sides are better than the other places, not only in taste but also selection--they have fried egg!
The restaurant is a little small, and they're usually pretty busy, but if you've got a group of 6 or more you can call ahead and make a reservation! Otherwise you'll just be waiting for your name to be called.
The service is solid here--they let you choose 3 meats at a time, and they're pretty lenient if you wanna choose 1 or 2 more.
You can't go wrong with Manna.
