Hat Creek Burger Company is a great place to get together with other parents while the kids play. They have an outdoor playground you can easily watch from the tables. They have an indoor section that is air conditioned, an inside section that does not have air conditioning but does have fans and TVs, and a couple of tables outside.
The playground set has a slide and several climbing options. It has a play grill and storefront for kids to play pretend. The ground is covered in springy turf, which is really great for kids to play on. The playground is also pretty bug free, which is nice to have as an option.
