Great $200.00 Hamburger

The Spruce Goose Cafe has great food and is a fun destination. Also Tail Spin Tommy's Flight School has Cessna 150 and 152 Trainers with excellent instructors.

Good diner

The Spruce Goose is on the field and has great diner food. Aviation theme is fun, service is fast and the view of the planes is great.
