The Cubs will field new concessions items this year, and the name of this game, at least as far as food is concerned, is bison. The lean red meat appears in just about every item they could think of, including hot dogs, hamburgers, and meatball subs. If you’re more of a prime rib and jambalaya fan, hit up the Sheffield Grill. The restaurant, which in past seasons was used for private events, will serve a buffet before each game. Even the plebes in the bleachers have new food to taste — this season’s hot dogs are from Sarah Lee.
