Best place to watch baseball in downtown JC is definiteLy Harbor Casino. This is definitely an Yankees bar. It also has the Sunday ticket for all you NFL fans. The other good NFL bar would be York street tavern, where they pretty much cater to all NFL fans. I have heard good things about White Star Bar in the Hamilton Square area of JC, but never been there. The best soccer bar in Jersey city is Dorrians, where you will have a good time watching Champions League, World Cup/Euro and EPL games, but they are lacking in La Liga games, especially when the biggest soccer game in the world these days is when Real Madrid play Barcelona, doesn't matter what the circumstance.
