Ate here a couple of days ago with a bunch of friends after finding myself in Tavistock. Delighted to find it listed on the Happy Cow site, otherwise we would have been a bit lost for a decent meal (thanks to the app on my friends phone)...
They have lots of veggie options and some good vegan choices. Food is made to order and they were really happy to adapt things. We ordered lots of potato wedges and a vegan mezze plate to share and four different vegan pizzas. All was very tasty and we would be happy to return.
They also serve fresh juices (apple & ginger was YUM!), herbal teas, fresh ginger and lemon or fresh mint tea. Lovely energy.
They do a gluten free pizza base too... which worked perfectly for me.
Cons: Serves meat
