Lento is more concerned with being a local then it is with being vegan. There was only one vegan item on the menu and several vegetarian items amid an extremely meat heavy menu.
The menu changes often so your experience when local veggies are in season may vary from ours in the middle of winter.
If you are brought here by a group of omnivores, you will likely find one entree to choose and perhaps some other items you can alter. Not recommended for vegans on general though.
Cons: Meat, meat, meat, Few vegan choices , $$
