Selection,
This will be my second trip to Phoenix, so by no means am I an expert. But the first time I went I didn't see any decent sports bars in the Scottdale area. Scottsdale was more the affluent area with upscale shopping, clubs and resorts.
I went to Majerle's downtown. It was billed as one of the top ten sports bars in America, but I wouldn't recommend it.
I had a better time at Alice's Cooperstown. I liked their big screen TV's better and the sport channels available. I also liked the food better at Alice Coopers than Majerles. It was located a few blocks to the south and east of America West Arena (at least that was the corporate name when I was there).
