Been there to order glutenfree Pizza. I could see with my own eyes tha they opened Schär Pizza Base Item and took it into oven. They charged 15 Euro for decorate a Product out of a box. Otherwise very friendly. A little to tiny space to come with more people.
All pastas and pizzas can be made glutenfree. It's a real Italian restaurant. The pizzas are okay not very special. Make a reservation, it's a very busy place even on Mondays
