Found this place on the second attempt, a few blocks north of the R-1 bus station on Ave. Tulum coming from the hotel zone, near the city hall (look for the Mexican flag) and 22 sm. Both the food and service were very good. It was a small restaurant with perhaps eight or nine tables. We ate our Saturday lunch at an outside table. It was rainy but the big umbrellas around us helped to keep the rain out. The only complaints would be the flies and the occasional street vendors walking up and down the street, but both would retreat at the wave of a hand.
