Disclaimer: This bar is not for casual drinks or for having a nice dinner with your family. This place is for heaving college drinking, listening to some pretty spectacular karaoke, and stumbling into your Uber after you close the bar down. So if that's not the type of crowd you're looking for, then this isn't the place for you.
This place has some really cheap drink specials every single night. $1 you call it shots on Wednesdays and super cheap 24 oz beers on Thursdays (less than 3 bucks for 24 ounces!). I'm pretty sure they have a special for every night, so I'll come back and edit with the exact specials when I find them.
I usually go with a large group of friends on Thursday nights. Karaoke starts at 10pm, but we like to get there by 9 so we can get a table (it gets pretty packed with college students for karaoke). The bartenders are always efficient and friendly. Karaoke night gets pretty boisterous, but there are some pretty decent regulars that always give the crowd a good time.
Pro tip: the karaoke host (I think his name is Steve?) might bump you up on the list if you do a jager shot with him :P Also, they have security who ID everyone no matter what so no ID no entry. And they have a swipe so fake IDs usually can't make it in the door. They never have a cover and they're really close to the light rail. I really can't rave about this place enough. This is by far my favorite dive bar in the Phoenix/Tempe area.
