A locally owned bakery and café that’s developed a loyal following after 20 years in business one town away is set to open a new shop in the former Bruegger’s Bagels location in downtown New Canaan. Upper Crust Bagels signed a lease Wednesday and will open in one to two months, according to owner Charly Sahlia. Sahlia said he’s been hoping to open in New Canaan for a long time but has found rental rates on Elm and Main Streets cost-prohibitive. The town is “very family-oriented, with a lot of kids and there are businesses there we can cater to,” Sahlia said. “But what we pride ourselves in creating at Upper Crust is it’s a ‘neighborhoody,’ healthier alternative to lunch and breakfast,” he told NewCanaanite.com.
