Unless you're very lucky or very living at home, lunch is little more than an expensive, joyless necessity. At least make that joylessness cheaper, with LunchtimeDeals.com. NY-based Lunch texts neighborhood-segregated noontime grub discounts straight to your cell -- saving you money like homemade lunch does, but with little chance you'll leave your phone moldering in the fridge. Just select a deal from Lunch's website, then enter your digits, and they'll text you a savings code -- to redeem, just flash your cell at the cashier/waiter, who'll be crestfallen when he discovers you're not inviting him to check out your ex-gf revenge smut. Lunch options range from 10% off Greek grub at Gus' Place (Greenwich Village), to 20% off Italian at Dolce Vita (Little Italy), to 50% off meals at Baluchi's -- in Downtown, the Upper East Side, the Upper West Side, and everywhere else antacid is sold. Though just now in beta, Lunch offers deals in far-flung metros including Boston, LA, Chicago, Atlanta, and DC -- though you know traveling's a joyless necessity when you're thousands of miles from home and still have to worry about lunch codes.
