Eaten here several times. Good gf menu of mains and dessert. Knowledgeable staff. Never had a problem
For our 1.5 week stay in London, I ate at this location twice and another location (Bayswater) once and never got sick. Their gf crust was actually really good. There is a dedicated gf menu. I only ever ordered the four cheese pizza so I can speak to anything else on the menu.
Amazing gluten free pizza and beer! Highly recommend
