Fenway Park has gotten a little tastier: The growing Tasty Burger chain now serves burgers on the Yawkey Way Concourse, says Adam's Hospitality. It's just down the street from the original Tasty Burger at 1301 Boylston St. Last month, owner David Dubois told me that he has changes in store for his Southie branch too: outdoor seating, delivery service, and onion rings. Here's a Facebook shot of the newest Tasty.
