I found it on Google maps, there’s one in Porto as well.
I’m going to suggest it 👍

Be prepared, it's a bit of a squeeze, and likely not to everyone's taste, but we enjoyed it as a change.
There was also Salsa dancing in the street at near 'O Melhor Bolo de Chocolate do Mundo' on Ave. Liberdada - not sure when exactly but it was fun to join in.
Enjoy
