Cleveland’s most buzz-worthy cocktail celebration is shaking things up this winter. The Cleveland Espresso Martini Festival, in association with OYO Vodka. This one-night-only event brings together Cleveland’s top bars and restaurants, each presenting their own unique take on the espresso martini — from bold and boozy to smooth and silky. Guests will sip, sample, and vote for 12 Espresso Martini recipes as participating venues compete to be crowned Cleveland’s Best Espresso Martini. This event supports Haven Makers non-profit - dream bedroom makeovers for children with cancer.
