What town are you in? I just moved back to Calgary after living in Los Gatos for 4 years, so I might be able to offer you some advice.
In my experience, most sports bars and lounges in and around San Jose televise every Sharks game (though all bets are off if the 49ers/Raiders/Warriors are also on, depending on the establishment). Hockey may not be as big as pro football, baseball or even basketball down there, but I'm sure you'll run into your share of Sharks fans. They're more passionate than I expected.
