There is a MASSIVE beer list; literally a small phone book of beers, so it can be fairly overwhelming. However, WOB puts out a featured beer list of about 40-50 beers and they update it often. Makes choosing something much less frightening. It's definitely a good place to go if you're a beer lover and/or an adventurous beer drinker. I would say I don't really fall into either of those categories but I've never been disappointed.
Tip: DON'T BE AFRAID TO ASK FOR SAMPLES. There is no shame in it. If you really don't like it, don't buy it. Ask for another sample. I had to ask for three one night and the waitress obliged. I finally found a fantastic beer - a White Chocolate Ale. Wow. So I'm slowly expanding my beer choices.
Expect a college bar vibe with lots of TVs playing college sports, trivia nights, food being delivered, random guys playing guitar on the upper level, so-so staff (some were really great or really off) and the crowd that an ASU-Mill Ave bar attracts. The beer list made me give it four stars. Really there's not much else that distinguishes this place from other chains. Just a good place to meet where everyone can find a beer they like.
