So few options in Salvador for vegetarian food - this is a buffet oasis, albeit expensive at R$36/kg. Right in the centre, just off the huge square, near the golden church.
Beware they do a few chicken and fish dishes - ask and they will happily tell you what is vegetarian.
Open 11.30-4 Mondays to Fridays, 12-4 Saturdays, closed Sundays.Pros: Decent food, Great location
Cons: Easy to pick fish or chicken, Expensive
