I frequent Blue Martini at least once a month and love the atmosphere this establishment provides. I find the early evenings to be the most enjoyable as the patio seating/live DJ almost has a Miami vibe in an otherwise normal shopping plaza (Town Square) of Las Vegas.
Here you will find a large local/industry based crowd as well as some wandering tourists. The drinks and food are great and Wednesdays is Ladies night.
If you plan on going to party here please be advised they do have a dress code for the later hours, so please save yourself the trouble and come proper! You can also get bottle service here for a reasonable price and is always a more fun route for groups of people.
The crowd is diverse and I have never had any issues inside. Well staffed, and attentive security.
Definitely a local hot spot and worth the trip if you have never been! : )
