Fenway smash-hit Tasty Burger says it plans to complete its expansion to Harvard Square next month. Owner David Dubois tells the Herald that "the two-level, 180-seat restaurant is slated to open in September at the former 7-Eleven location at 40 JFK St." That means this Tasty Burger will be bigger than the original location and also bigger than the planned Southie expansion, which the Herald says is on track for an opening "in a few weeks." While that Tasty will be to-go only, expect the full experience in Harvard, with beer, wine, and pool. And burgers. Tasty ones.
