There is not that much around the Cala Gracio - its a lovely chilled area.
You must pay a visit to the beach cafe / restaurant at Cala Gracionetta (little beach at the side of Gracio). Its idyllic.
You are not too far off the Sunet Strip side of San An if you are in C Gracio. The Golden Buddha,Kanya and Coastline region are the first bars you encounter as you travel back towards San An.
There are also regular bus services from the bus station in San An than run through to Cala Gracio.
Its not too far to walk though.
