I’d advise against coming all the way to Santa Rosa just for a game watch. I’m actually in Santa Rosa now, although I live a few miles north. Santa Rosa is not particularly close to St. Helena or Napa. Unless they want to check out the new Russian River tasting room or have the mega sports bar experience @ Victory House, there are plenty of decent options in Napa County, which will save a lot of windshield time. My $0.02.

But I was also thinking about Calistoga.

I've only been to go to Chateau Montelena, but it's fairly close to St. Helena, and it seemed like there might be a few places with the game on.

That said, I've never stayed in Mt Helena, just drove through, but it appeared there may be places to watch the game as well, that isn't just a wine bar. I seem to remember some nice restaurants that had very good bar setups throughout that northern Napa Valley area.
