Bethesda Bagels is planning a late September opening at Wildwood, where it’s been under construction since last winter in the former Coco Blanca space near CVS. Owner Danny Fleishman says he hopes to open in time for the Jewish High Holidays, which begin on Sept. 30th this year. This will be the fifth restaurant for Bethesda Bagels, a family-owned enterprise that’s approaching its 40th year in business.
