Pizza Express Of the chain restaurants, this is our favourite. They now have a vegan menu. The Giardiniera - which is very tasty, is automatically vegan. Some of their other pizzas (such as the Veneziana) can be veganised . Pizza Express state it is important for you to mention how strict your diet is to the manager on duty, so as the chef can implement all necessary procedures to avoid cross contamination. On request their dough balls, bruschetta and garlic bread can be made without dairy, substituting olive oil instead. https://www.pizzaexpress.com/vegan-choices

Basilico Pizza Branches in North, Central and South West London.
