Got ripped off on my birthday. We had a large party dine at Osaka which automatically added for gratuity due to the number of people. Well on top of the already decent tip the server helped himself to an extra $10. I took my copy of the reciept and my bank statement to the manager for them to correct it and she said that she needed time to ""look into it"". Seems like the restaurant is ok with this behavior. If you go to eat there pay cash.
You can also find better food elsewhere.
