This place is the ultimate Tempe dive bar. In my opinion this place is in one of the sketchiest strip malls in Tempe. I could write a review on the parking lot alone, but that is for another day. Anyway, enter the Yucca Tap and go to the right and you will see a depressing, dimly-lit bar. To the left is a well-lit whiskey/beer bar.
My wife and I visited the Yucca on a random Saturday night at about 8:30ish. The place wasn't too busy...yet. We first went to the right. We each got a beer and had a seat in one of their many booths. There was a small band on stage. There were only a handful of people there and most looked like they had been there all day drinking away their sorrows and/or hiding from the law. The place was pretty depressing. However, I like cheap drinks, friendly bar tenders and dive bars so I was ok with it. Not exactly a place to bring your wife though.
Anyway, the other half of the bar (to the left when you enter) is a totally different story. They have a great selection of beers and sort of reminds me of an older, grittier Taste of Tops. We sat there for about an hour, sampled some more of their beers then took off.
I will definitely return when I feel the urge for some local dive bar action. The entire place isn't as bad as it looks, has cheap drinks and everyone seemed pretty friendly.
