Tried a number of the stands. The old rule still applies: if the stand is a name brand, it's likely to be good. If it's a generic stand "Fan Favorites" it's not very good.
The roving hot dog vendors. In the old stadium, the vendors carried around a metal steaming oven. He then assembled the hot dog as you ordered them. Now the hot dogs are pre-assembled and kept in the familiar cafeteria foil wrap. The oven has been replaced by an insulated carrying caes. The dogs are cold and terrible.
The sliders at the generic "Fan Favorite" stand (dry)
The garlic fries at the garlic fry stand (the garlic is too weak)
Carl's Cheesesteak (bit bland, long line)
>The Primo Italian Sausages (better than the old stadium, larger, grilled longer, more veggies)
>Johnny Rocket's Cheeseburger
>Johnny Rocket's chocolate shake
>Meatball "Parm" Hero at the Italian deli in the Food Court (BUT the "Parm" is a lie...no cheese on top..."it's baked in" they said)
Nothing's cheap, but some of it is worth it.
