I have tried americano and Maple story.
Americano isn't better than any other coffee shop selected as best coffee in Las Vegas but isn't less than those, too.
If you want to coffee late evening and live in Southwest, this place would be another choice of Madhouse coffee. ( a little far from Southwest area)
Try Maple story( I am not sure of the name, but kinds of honey toast) is very sweet but really good. Try today and diet tomorrow. It is worth to get at least once in your life.
Korean guys are usually kind and generous to customers so nothing here to get down due to the bad service.
