Rittenhouse’s Meritage is switching up its happy hour action again. Starting tonight, and every Tuesday through Friday evening until the next changes come, the restaurant and bar is offering buckets of Corona ponies and cans of Sly Fox at reduced prices between 5 and 7 p.m. But cheap brews aren’t all. There’s also some new cocktails, including June Bug, cucumber, vodka and St. Germain, and Summer Jam, tequila, lime and Chambord. And snacky things like Korean pork tacos, kobe-stuffed grilled grape leaves, and corn and crab fritters are available for $5.
