The burger at Radius has earned itself quite a following since its debut – and now its fan club is about to get even bigger. During the month of April, the award-winning sandwich (no seriously – it took top honors at the South Beach Wine & Food Festival back in 2008 and has been singled out for its deliciousness by Boston Magazine and Epicurious.com) will be offered at half its original price for Saturday night diners in the bar (not in the dining room or for take-out – just in the bar). Beverage Director Daniel Motsinger will be on hand to help you find the perfect beverage accompaniment, so swing by High Street to see what all the fuss is about. Call Radius at 617.426.1234 for details or directions.
