A very large square links the Palace of Turin and the Commercial Street, and straight along the Commercial Street is the railway station. On rest days, there will be a lot of people on both sides of the square and the commercial street performing arts. As an amateur, I think the standard is quite good. There are old choirs, young bands, artists who play with empty barrels, and soloists... They don't make you feel like a financially hungry marketer, but rather perform for pleasure. Holding a pile of coins to watch the show all the way, giving some support to your favorite show all the way, and you won't get tired of spending an afternoon strolling around.
