You’d be a hit at the races (wide-brimmed hat, mint julep in hand). But, really, a horse is a horse (of course), and there’s no sense schlepping to Kentucky if can watch — and wager — in your own backyard. Starting tomorrow you can at Stretch Run Sporting Club & Grille, a two-level River North joint with 217 TV screens (ranging from 32 inches to ten feet) and all the sophistication you crave (think Kobe beef sliders, not sloppy joes). And then there’s the action. Take advantage of the club’s Off-Track Betting license and win big when Sophia’s Pearls (the stallion that reminds you of nana) comes through at the finish. Whether you go home with a fistful of cash or an empty pocket, you’ll be satisfied. You can bet on it. Stretch Run Sporting Club & Grille, 544 North LaSalle Street, at Ohio Street (312-644-4477 or stretchrunchicago.com).
