Just a brief round-up of some casual vegetarian spots in Stockholm.
Primo Ciao Ciao on Bondegatan is obviously Italian, and generally packed for dinner. They serve good pizzas and pastas for about $30 a person. It's veg friendly, but there is plenty for the carnivore.
Chutney on Katarina Bangata is a very casual vegetarian restaurant - you order at the counter and they bring you your food. The baked chevre is quite good. It’s cheap by Stockholm standards – about $20 per person.
Hermans is on Södermalm, but not in SoFo. It’s a vegetarian buffet and there are wonderful views if you eat outside. It’s at Fjällgatan 23A. It's also about $20 per person.
