Hi, flamango/Heather.
Such an event is taking place this Wednesday when the Internations group are meeting at 19.00 at the Villa Saroli Ristorante, Lounge & Bar.
Joining is free.

Choose Switzerland then find Lugano expats.
At the moment there will be 105 attendees (11 from the USA) representing 38 different nationalities. Plenty of English is spoken but you can certainly practise your Italian if you wish !
Best of luck in Lugano !
