There's one where you get your parking and dinner at Shake Shack included that seems to good to be true.
I really liked the Shake Shack, but do you really want to be limited to a sub-set of food options at the park? And the lines at Shake Shack are ridiculous, I wouldn't touch this deal unless they pledged to double their service capacity. I haven't tried the Mexican or Frites places yet, but the BBQ was bland, so I couldn't imagine wanting to eat at one of those four spots 20+ times in a season.
The seats for this deal are in the scoreboard area, which isn't horrible if you are going with friends and plan to socialize more than watch the game. For my money if I were buying a full season plan there is no question that I would forego these gimmick promotions and get something in the area of TBSITH.
