If you’re thinking of popping the question this Valentine’s Day, then consider a “Martini on the Rock” at New York’s Algonquin Hotel. The sparkly concoction conveniently comes with a diamond dropped into the drink — and it’ll only set you back a minimum of $1,000 (or cost as much as you’re willing to spend, depending on the choice of diamond, naturally). Said price tag includes a meeting with the hotel’s preferred jeweler to pick the stone, and the purchase and appraisal of the little bauble. If you’re already married, here’s a little tip: Ordering this toddy will still score you (major) points with the missus. Reservations are needed 72 hours in advance.
