At last, an opening date has been tossed out for the Harvard Square expansion of Tasty Burger: this weekend. UrbanDaddy shares that news, saying the date is tentative, and that food will indeed be served until 4am as previously reported. Tasty Burger got its start in Fenway and added a take-out only location in Southie in September. Previously, this space was a 7-Eleven. Yeah, this better. Stay tuned for confirmation of the exact opening date and get ready for Cambridge's first taste of the Pulp Fiction-inspired Kahuna Burger, with pineapple, grilled red onion, and teriyaki sauce.
