The food here really is fantastic, but we made the mistake of tipping 15% instead of the 20% the waiter was expecting. If you google tipping practice in the Usa, you will find 15% is still the standard tip even though some higher end restaurants are pushing for up to 25%. Ok, that's fine as long as the customer is made aware of their expectations, and it indeed a higher end restaurant. Well, upon paying our bill and taking our leave, the waiter confronted us and demanded more tip, saying he was nice to us so we should give him more money for this. It was extremely embarrassing, and soured our dining experience. He did not get more money, and we left. I think this tipping custom is getting out of hand. I wish North American restaurants would take a hint from their European counterparts and just add the tip to the bill and everybody is happy.
