i also have the same disappointing experience with this restaurant. Even if your paying 175, i think Nobu grill should prove its worth so customers will patronize them, much more 349 for buffet lunch. Their service is so poor that attendants keep on shouting at each other when they ask for something, considering customers were in front of them.
And if there is a cockroach in that restaurant based on past reviews (and I believe them), i will never ever go back again. What for? their food is bad, service is poor and their place is dirty. Even for 50pesos value meal it's not worth.
