I just visited the Prudential Center in Newark, NJ and was very impressed with the facilities. I went to see the New Jersey Devils game and all the viewpoints in the arena are very good in the arena. The lighting and ambiance of the arena is much better than the Devils previous arena up the road in East Rutherford, NJ.
The food in the arena is excellent. If you are hungry, try the Angus Cheeseburger, easily well worth the 9.50 price as you get a great piece of meat and a large portion of french fries. The pretzels are also good but not as soft as I had hoped.
If you are fan of the team, there is one souvenir store "Devils Den" outside of the arena as other concessions inside the arena. Just one more note: If you are fan of a rival team, especially the New York Rangers, you will hear derisive chants and other words during the game as the teams are bitter rivals. Also, the train station, Penn Station is nearby.
