For kids they had hot dogs (nice ones, like beef foot longs, or polish sausage types)
Chicken fingers, not McNugget type but nice ones. There were burgers as well.
Lets see, what I remember seeing...
There were fajitas (thumbs up from DH--chicken /beef or combo)
Atlantic Salmon
Chicken Pesto (I had that it was wonderful)
Burgers
Hot Dogs
Chicken Ceasar Salad
Another Chicken type salad(these entree salads were huge)
It also came with a huge drink, choice of appetizer,(we both picked a side salad, but they had potato salad, cole slaw, etc), and desert. Desert was everything from red/blue jello with whipped cream layered (saw lots of kids with that) to carrot mango cake, to cheesecake, to a triple layer chocalate cake, and HUGE cookies.
You can buy drinks at stands. There was a stand right near the lockers.
We didnt bring any extra money, we only budgeted for the picture, and tacked it on the credit card.
