Been going here since they opened. The coffee is really great. My only complaint is they allow smoking on the small outdoor patio at the entrance. I have noticed it has become much worse lately. Perhaps because most other shops have banned it so the smokers come here now. I moved inside last week and the smoke comes inside when the door is opened. Its a real problem. It is still very worthy of my 4 stars.
.UPDATE: 07/14 :
Note my review went from 4 stars to 5. heard from Luiz,. I am not surprised. Sambalatte is the premier coffee house in Vegas and his reply was great. My review above was concerning the Boca Park location near my home. Luiz is in the process of making the patio nonsmoking and was really concerned. I am now a customer for life. No where (except maybe the 2 new locations) in Vegas produces coffee this perfect. Thanks Luiz!
