There will be another watch party tomorrow at Dave & Busters in Orange at 7:00 P.M. I went to the last watch party at the ESPN zone and considering it was the day before Thanksgiving, all the tables were filled with Ducks fans as well as the bar. The free stuff was pretty good. They gave away pens, foam pucks, championship banners, hats and key chains. There was also a raffle for a souvenir stick signed by Andy McDonald and KROQ gave away Ducks tickets.
So if you like an environment where you can cheer with a bunch of other fans (or boo) watch parties are the way to go. Here is a video of the fan reaction (from the bar) to part of the May fight that night. The bar area was a small part as they had the game on a huge screen.
So go and enjoy the party and cheer your Ducks! (and get free stuff).
