We know we’re biased, but we say this in all seriousness: Grub Street has just published its best Ask a Waiter thus far, and what we have to imagine will be the best Ask a Waiter ever. It’s with Dirty Delta of Lucky Cheng’s, and you’ll learn everything you ever wanted to know — plus much more — about being a drag-queen waitress. What does Dirty think about the East Village institution’s food, for example? “You don’t come to Lucky Cheng’s to eat gourmet food,” she says. “You come to see some bitch in a G-string acting crazy at your table.” But of course. There’s so much more at Grub Street.
