There is no doubt the food is incredible here, but....
The prices at Raku are high, and while you come here for the food primarily, the experience needs to be improved. The restaurant is cramped, hot, and dark. The service is extremely inconsistent, with servers disappearing for long stretches of the meal.
Even with the food being as good as it is, I can't see coming back to be hot, cramped, and ignored for a high price.
