The servers were the rudest I've ever experienced anywhere. I have no idea why they attended everyone around me but treated me like I was invisible. I had to ask for wasabi and was given a tiny amount and a scornful look. Wouldn't refill my water either. Is it because I'm American, middle-aged, a woman alone? I don't look or dress weird and none of those reasons are excuses to be ignored. I wasn't even impatient until I walked up to the service station to request some wasabi and 3 waiters acted like the couldn't see or hear me. I have no idea what I might have done wrong. A horrible experience and not worth the $20 I threw at them as I walked out.
