There is nothing else that I would say is a DEFINITE if you visit this area. As with all of the markets across Goa, it's vibrant and full of stuff to buy, eat, drink and dance to!
There's a stage half way through which has a variety of acts - we saw an amazing African group of tumblers (balancing/gymnastics etc) last time - they were astounding. There's a bar next to the stage area, so you can sit with a chilled Kingfisher, listening the music or watching whatever's going on, and overlooking the lake.
An amazing place to spend your Saturday evening - just keep your valuables close and get your haggling hat on!!
