You just missed the same thread about a month ago, must have scrolled off the board.
Cheap, in front of Kraken, is Mama Stellas Pizza. The kids could share a pizza because it comes with a bunch of fries.
Quality, in the back corner of the park, you'll come to the Clydesdales, and next to them is the hospitality center where you can get a couple beer samples. In this building is a deli shop that makes fresh sandwiches. This is the place to go, the sandwiches are great. You grab a beer sample, then walk with the kids looking at the horses. Get there early at 11am or late at 2pm, because the place is packed at noon.
