I tracked this place down on Happycow app as it was the only one of 3 in Vigo that was open on an evening. super easy to find and a lovely meal.
a good mix of vegan and veggie things in the menu and I'm sure if you speak with the owner, whose English is good, they would adapt meals.
food is reasonably priced, I paid less for a 3 course dinner and wine here then I did in Santiago for salad and pan con tomate! the food is a little old fashioned, British folk might recognise some Crankies influence. but it was lovely like a big veggie hug of home cooked food made with care and respect.
Cons: this is not fancy food, its just good food
