Javier's is located in the Aria hotel in Las Vegas, NV. My wife and I were in town for business and we decided to give it a try.
The vibe is very cool with a very interesting decor. It was dark, not too loud and overall very cozy.
We chose to sit at the bar and were we greeted and placed our drink orders very quickly. The bartender made our delicious drinks (Javier's Margaritas) right away and took our appetizer order of chips and guacamole. It came out quickly and was delicious. The chips and salsa with the guacamole is a must order.
For diner, my wife ordered the carnitas and I ordered the enchiladas with chicken. Both were good but both were served at room temperature. If they would have been hot, we would have no complaints.
Overall, the drinks, food and service were all good. If you are staying in the Aria or across the street at the Vdara, I recommend giving it a try.
