There are way too many to list. Many restaurants and cafés offer free wifi. Our teenage daughter MUST stay connected so most places we visit we just ask, most are happy to allow you to connect to their service.
Free WiFi has become a selling point for a lot of bars and restaurants. They'll make it really obvious when it's available hoping you'll come in and spend money on food or drinks. Don't choose a place based on this, but you can probably find it available where you'll end up anyway.
