I've tried many different coffee shops in many different cities and countries and I keep coming back to 21st Street. I won't say that I know a lot about coffee, but I will say I drink a decent amount of the stuff and have developed a taste for what I like and what I don't like and 21st is the best. They use some of the best beans (Black Cat) and they usually have another espresso option and they are always able to tell me a little about it. The staff is super friendly and can be talkative if you are in the mood. This is another one of those places that already knows my order when we come in. If you need or want some coffee and are downtown or in the Strip District, give them a try! You will not be sorry!
