Flamenco Dance Shows Sitges, Spain?

In Sitges there is nothing like that.

The point is that flamenco is from Andalusia (in Southern Spain) and Sitges in Barcelona belong to Catalonia, where we do not really feel Spanish.

In Barcelona there are such shows, but you must know they are nothing but tourist traps, as foreign tourists are the only ones who attend those shows. If you go there, you will be overcharged and will see something not typical of the area and of bad quality.

If you are really interested in flamenco, go to Andalusia.

No.

It is not part of the local culture.

There are occasional performances but they are very rare as the locals do not like flamenco dancing.

There are some reasonably good shows in Barcelona which is only a short train trip away. Night buses run all through the night.
