For a city that never sleeps, there really aren't that many coffee shops open 24/7 in Las Vegas. At least there is Madhouse. At this point, the Monkey Mocha iced coffee I ordered is already halfway gone. 10/10 would recommend if you're into peanut butter coffee drinks that taste like dessert. I usually get a Mad Cow latte which is hazelnut based (can you say nutella in and around your mouth?) The atmosphere is great and I usually come here to study. One time, my friend came in with a starbucks cup, and one of the employees told her to throw it away. Down with coffee chains!
