3363 Post Road in Southport is no longer the home of the $5 footlong, but that doesn’t mean there’s not a deal to be had. In the bones of a former Subway franchise, right next to Dunkin’, is Hotaru, a predominantly Japanese restaurant where the star of their show is a very affordable omakase experience. Hotaru opened very quietly to friends, family, and random curious customer walk-ins on March 16 with an abbreviated menu that’ll soon expand. The team behind Hotaru is Yingying Yan, who owns Gingko Sichuan Cuisine in Fairfield, her chef at Ginkgo, Jerry, and Ken Piao, the owner of Yuki Kitchen in Westport.
