Let me just start off by saying that the Roka Akor in Scottsdale is much better. That was one of the best meals I've had in a long time. The one in Chicago is certainly not bad, but there is some room for improvement. Let's start with the good: the service is attentive and friendly, the atmosphere is great, and most of our dishes were great (specifically the grilled pork belly, tuna tataki, and the wagyu/kimchi dumplings). However, some of the other dishes were not nearly as enjoyable. The sushi was good but didn't wow us, and what disappointed me most of all was the wild mushroom rice hot pot. When we had that in Scottsdale, it was absolutely to die for, but here in Chicago it was just okay. This place is expensive as well, but if you order the right things, I can assure you that it will be a good meal.
