I have a rule which I don't always keep, not to visit Irish pubs when abroad. However I was tempted into the James Joyce when passing by and noticing the wood panelled interior.
This is a lovely pub with a great atmosphere and a wonderful history. One of the very professional staff kindly gave me a book about the history...
Not a pub, not a restaurant but a bar that serves a great burger (and other food). Close to Rennweg tram stop this friendly bar boasts the best burgers in Zurich. Good range of ubiquitous beers from Boddingtons and Guiness to Schneider Weiss and Hurlimans.
