I can recommend the two locations I have visited: Beaconsfield and Amersham. They are both similar in atmosphere, modern and stylish with a bar area which is buzzing at the weekends, and the menu is the same for both.
Their menu is extensive and you will have plenty to choose from and every so often they update their options. Here are my favourites – seriously, there is a lot more in their menu –
Start with the selection of breads and olive oil, hummus and puccia bread
The Pizza is delicious, you can either choose a select option – Usually changes from either a ‘No-chicken’ pizza or a ‘No-meat’ meatball choice -. I personally always get the (Vegan) Margherita and add a selection of vegetables on top!
If you’re in the mood for pasta, then try out the Rigatoni All’arrabbiata, and if you want, you can add NoChiken!
They always have a good Vegan alternative in their burger menu, with more often than not, a second option in the daily specials!

For dessert, they change up every few months. From a delicious olive oil chocolate chip cookie to a Belgian Chocolate & Raspberry Torte. And if chocolate is not your thing (What!?) try out the Sticky Tofee Pudding it is seriously exquisite and comes with salted caramel ice cream (Vegan of course)
