    Really enjoyed Siempre. The food was delicious (street corn, shrimp diablo, enchiladas). We also had margaritas and they were great - not too sweet and super tasty. We never felt rushed and the service was attentive and friendly. We will be back.

    Siempre J.B. is a great spot. Welcoming & chill vibe, friendly & attentive service (Thank You Shane & Camilla), nice wine list, and a delicious menu. Our favorite bite is the Enchilada, Taco & Tostada Entree. We recommend Siempre J.B.

    food was good - service was trash- sat for 20 mins and no server came over - the bartender saw us waiting there and came from behind the bar to get us started and then still didn’t see the server for another 10 minutes and wasn’t attentive the rest of the time. food was good but if the service was good could have made it even better

    The food was exceptional, but there were multiple items that were not special or would need to be ordered again. However, the tacos and basic Mexican staples were great. Every drink was a winner. Service was fantastic. Will come again with proper expectations in mind.

    Ive been to Siempre several times, everytime has been a great experience, in my opinion, it's the best Mexican food in Las Vegas, food was fresh and extremely good, service was excellent, atmosphere was great, a lot of thought and care had been put into the decor and it shows. I will be returning for more.

    Great service and food! Everything we tried was delicious. We had the wagyu hot stone, oysters, yellowtail, and diablo shrimp. The shrimp was good, but not our favorite. Everything else was amazing!

    Portions are SMALL. Don’t sit in the booth at the back—the light from the kitchen is blinding. (Management, if you are reading this, get a full height swing door into the kitchen)

    Went there for our first time! Service was outstanding food amazing, our only issue was the loud music & it was dark - hard to read the menu! We will go back, probably for lunch. One super cool thing was they use real coke products from Mexico !
