How much should I tip in a New York restaurant?

Q I am going to New York for the first time in November. What sort of percentage would you suggest as tips in restaurants?Peter EA Except in extreme circumstances, the minimum you should leave is 18 per cent. This is, I agree, a ridiculous addition to your bill, especially as it is in addition to the 8.875 per cent sales tax on restaurant meals. The two combine to expensive effect. If you order a burger and a drink for two at a menu price of, say, $39 each, the total you would pay is over $100.
