Been here a few times as we like the setting. However last time we went it was not long after the rains and the place was inundated with flies - we had a drink and moved on - see windermeregolfers review of the bar at Caldereta.
The problem with Diferente is they don't have a lot of choice on the menu. Not overly cheap because of the setting and lack of competition, but what they do have is nice enough.
