I've been to a handful of vegetarian restaurants in the Dominican Republic (all listed in happy cow except the ones in Punta Cana) and this is the best so far. The setting, staff, variety, and price are all great.
As another reviewer stated, the map is wrong. If you are going down Tiradentes from Avenida Kennedy, you will have to turn right onto Salvador Sturla, not left. The street dead ends and it's surrounded by no other businesses and there is no sign. The fence is painted green and the seats are located just at the end of the driveway.
