Not too expensive but not a lot of choices. They don't allow you to bring anything in with you except for bottled water. They do have water fountains.
It's mostly like gas station snacks. Small bags of chips, Rice crispy bars, waters and Gatorade. If I remember correctly they are usual gas station prices. 1$ for chips 2$ for drinks etc. Save your money and bring your own waters though.
Hey you will be fine with 20 dollars they have a snack area. I take my son for a few hours and after we just go or out to lunch
