Monday is Pi Day (3/14), which means OHSO Brewery locations will be holding their annual pairing of 11 pie-inspired beers with 11 pies from Pie Snob starting at 11 a.m. Monday and continuing while supplies last. In downtown Mesa, Cider Corps, normally closed Mondays, will open at 3:14 p.m. to tap three new flavors – Brambleberry Pie, Cherry Peach Pie, and Key Lime Pie. Eight-ounce pours will be $3.14.
