I did not have high expectations on service based on some of other reviews, but I never would have expected to be fully ignored while making eye contact with multiple waiters for over 5 minutes upon entering and standing right by their host desk. Also took over 20 mins to flag down someone to take our order (no one tried to come talk or even make eye contact) and never once got our teas refilled. We felt literally invisible as it was pretty clear that they were much more proper and attentive to some other customers - and bear in mind that we gave no attitude or anything whatsoever.
Food was okay. The tsuke tempura udon only had 1 shrimp tempura. The black sesame udon was not bad, but just a bit strange because it was on the sweet side (also had very little toppings). Not the best udon by a long shot in my opinion and not worth the price or the wait, and especially the frustration of dealing with their poor customer service. Truly do not understand the hype.
Side note: they tried to bring us a drink and a third udon that we didn't order on separate occasions.
