If you are looking for something different to do in Milan, how about a night of billiards. Whether its after work or after dinner, Bar Euro Jolly will make for a fun night.
It is in an unassuming spot, right before the restaurant Seven, and around the corner from Porta Genova. Walk through the front bar, through the area of videogames and a fooseball table and you will get to a room of 25 Pool Tables. There are enough that on a Friday night, you will be able to get a table in the back.
This place holds tournaments and events and if you are into pool, you can ask maybe if they have a team, you can join. But if you are going just for fun, order some beer, grab some friends and it will be a good time!
