There are covered areas and benches but I strongly recommend that owners stay with their dogs if they are in the park, playing with other dogs. The owners should be responsible enough to pick up their dogs' poop and help maintain the park.
There is a covered area right outside the fences with about 3 or 4 picnic tables. There are rock benches inside the dog yards, but food isn't supposed to be brought in there.
There are a couple of picnic tables outside of the fenced doggy areas. There are stone benches inside the fenced areas. I have seen food trucks there before with food for people as well as pups.
There is a covered pavilion type stucture right outside in between all the dog parks which has a few tables you could eat at. But no food is allowed in the dog park area.
Saturdays and Sundays they have a vendor that has delicious food. They do have an area where you can sit down.
