So, it's 9:35 on a Friday and Xtreme Bean is the destination- why? Honestly, it's only because they've got the only game in town. That's right, America's largest public university is served by exactly 1 coffeehouse that is open to midnight. Cartel recently pushed their ridiculous 8pm close to 10pm. But no one else does the late night thing except Xtreme Bean.
In fact, the extended hours and generous sizes are still all I can recommend. As ASU has grown, XB gets more and more crowded. Good luck finding a table any night after 9pm. Plus, all the extra people also slow the wifi to a crawl.
So why am I going? It's coffee. It's a place to study. It's the only place open after 10.
Note to entrepreneurs-- want to make some money? Open a decent 24 hour coffeehouse a few blocks away from the nation's biggest university. Even though 60% of the student body are frat rats and future single mothers, the remainder need places to study that don't close when Mom falls asleep.
