Richard Coraine, chief operating officer of restaurateur Danny Meyer’s Union Square Hospitality Group:
At restaurants, see if you can bring your own wine and pay a corkage fee (anywhere from $10 and up). A good host won’t flinch. “I’d thank you for choosing my restaurant first, whether you brought your own wine or not,” says Coraine. Also, bottled water can be marked up by as much as 300 percent, so order tap.
