Verona itself is a multyethnic city, here you can meet people from all the parts of the world. Regarding tollerance, Verona is probably in the first place among Italian towns.
This guy from Peru is performing his amazing Inka music on Piazza Bra, right opposite to the arena, and many people stood around, both locals and tourists, enjoying in his performance.
It is why Verona is, besides many other things, so special to me.
If you cannot afford the tickets for The Summer Opera Festival at arena, which are pretty expensive, you can seat in one of the cafes of Listone and listen to the music.
Dress Code: The fourth side of the Piazza Bra has a grasefully curving line of buildings. The line of the buildings is further emphasised by a very wide pavement, known as the Listone, and it is here that many of the people of Verona like to take an evening stroll.
During summer the best thing to do is leave the hot Verona and go boogie in one of the fantastic nightclub on the lake....outside, with swimming pool and lake view.
A posh one is Hollywood in Bardolino ....you have to pay to get in but inclusive is your first drink, usually ladies don't pay or pay less then gentlement.
Dress Code: no dress code required, but better be smart as you have to cope with the italian fashion

Is there a nightlife in Verona? Maybe in the newer parts of the city. I didn't find any in the historic center. Even the cafes & restaurants close early. The only thing that was open late was a bookstore! And it had quite an audience.
Didn't do anything specific for nightlife, i.e. clubs, bars, discos, but there are quite a few summer performances in the Arena worthy of attending. for a schedule see: http://www.verona.com/
