So we all would rather see our favorite bands in smaller venues. However, the big venues bring in the cash money, so unfortunately we have to accept it for what it is. HP Pavilion is a pretty decent place to catch a show for an arena. It's pretty easy to access from the freeway, parking is plentiful (though not cheap), and the arena itself has decent amenities and food/drink selection. Since it's a hockey arena (as opposed to basketball), it is smaller than a place like Oracle Arena. So, you can get pretty decent views of the stage from wherever you sit. If you're on the floor, there is a concession stand and bathrooms down on the same level, so no need to climb the stairs all the way back up unless you're heading to the merch booth.
H ockey's the main event, but plenty of concerts too.
