Wonderful friendly little cafe/restaurant run by a Chilean family and serving up meals/snacks from that region. Not totally veggie but always several vegan options and soya cream available for vegan flapjacks for dessert.
Good size portions and very family friendly (sadly up steep stairs so not as accesible as you might want).
Deli/wholefood shop downstairs which has lots of tasty things.
Cons: Steep stairs for access
