Just got back from a quick business trip to PHX. We were staying in Tempe, doing some stuff on the ASU campus, so my comments apply mostly to that area.
We went to Papago Brewing a bit after lunchtime, which is a brewpub that currently contract brews their "house" beers, but is in the process of building their own production brewery. They have a pretty good selection, I want to say around 20ish taps, and I thought also a pretty good selection of bottled beers that were all temperature controlled, which you can of course buy and drink right there. Food was above average pub grub. Overall I liked the place and I really enjoyed their coconut coffee stout.
Later that day we went to dinner at OHSO eatery + nanobrewery. On paper, this place looked fantastic. This place actually had more beers listed on tap, MANY of them were house beers, which I found somewhat surprising due to it being a nano. I tried their house pale ale on nitro, house IPA, and also their English pale on cask. None of the beers were particularly impressive, and in fact both the pale ale and the IPA tasted pretty "green", which sort of makes sense given they are likely pressured to turn over their fermenters very quickly in order to maintain such a huge selection, especially for the more popular styles like IPA. The IPA in particular had a pretty harsh hop flavor and mildly astringent character that was off-putting. Food was mediocre bordering on bad. My friend's flatbread pizza was downright awful, and they removed that charge from our bill after we complained about it.
Next day we were in a conference all day, but I got a few recommendations from a local beer lover there at ASU who said his favorite local beer spot is Four Peaks Brewery due to the quality of the beer and food, followed by World of Beer due to their selection. Unfortunately I didn't get a chance to visit either in person, as we had a previous dinner arrangement and I ended up spending my last meal in town at Gordon Biersch, a block away from World of Beer. Gordon Biersch actually was good food and their Oktoberfest/Marzen was probably in the top 3 that I've ever had. It is a fabulous example of the style. It is, however, a place that I have easy access to here in LA so not exactly top of my list when traveling.
