I'll balance my review based on food, service, and atmosphere. For someone who runs a restaurant, I'll give it to Nobu that he makes good food. There are not many Japanese places like his around the area.
I've been here in total 5 times but it is no longer a top choice for me.
Food: awesome. He nails each dish with Japanese flavour. Even for something simple like Karage it packs a punch. Simple clean options that can give you that happy feeling.
Service: I don't care if he is a one man shop, for someone whose Japanese culture praises the idea of efficiency he fails. No information on where the food is. You have a huge margin of inconsistency for arrival of food. The pushiness is arrogant and to me yells desperation. It's very easy to make a simple appetizer dish that folks can nibble on while they wait. You cant expect to make people wait as long as he does. Maybe he's in a downward spiral and doesn't know how to get out. Who knows.
Value comes from the experience. If Nobu just does something to offset the waiting with small snacks, then I think people would be willing to wait.
But it's clear from the reviews this is a try it place without much commitment. If you are lucky enough to come when it's open, which I never know when it is, then absolutely try it out. But after that one round, I recommend you save your time and go to another place that actually puts as much effort into their hospitality as they do food because you sure won't get that here.
