When is ice cream yoghurt? When it's frozen yoghurt. And tubs of this wonderfully refreshing delicacy are being sold across Lisbon from quirky little portable kiosks designed as old-style ice VW camper vans. Made using natural yoghurt, fresh fruit and low fat milk, Weeel yoghurt is offered in a wide variety of flavours including strawberry, chocolate and vanilla. Little sugar is used so the calorie count is low. It's also gluten free. In fact, this is some of the healthiest street food you'll find in the city! The Weeel kiosk at Cais do Sodré serves passengers going to and arriving from all stations on the Cascais railway line, which serves several beaches along the Lisbon coast.
