I'm actually vegan & GF. They don't serve a GF base (this is a pic of their non-GF pizza), but I took my own GF base, and they dressed it with vegan cheeze- like any regular margherita! Charged me a bit under a usual price because I'd brought my own base, too.
ā If you're Coeliac, it still wouldn't be good to eat here as they warn of cross contaminatin. But if you're just intolerant (like me) it's all good š
