11. Saturn Café, Santa Cruz, Calif.

Saturn Café offers traditional diner food with a vegetarian, organic twist. It first opened its doors in 1979 with owners who were looking to create a community gathering place with a commitment to social and environmental justice. Their milkshakes are made with McConnell’s premium ice cream (though vegan shakes are also available) in classic flavors. After choosing an ice cream base, customers can choose from shake add-ins like chocolate cookie crumbs, berries, and organic peanut butter to make their shakes unique. The interior is an outer-space take on an old-fashioned diner, colorful and entertaining enough to bring along the kids.
