    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 !

    Really amazing mexican food! Carnitas have a real carnitas flavor and not the typical dry carnitas. Scallops with the rajas and cheese are delicious!!

    Our experience from start to finish from the time we walked in the door was amazing. We were celebrating our anniversary and they welcomed us with that and ended our dinner with a complementary dessert.  all of our drinks were delicious and our dinner was very tasty. Our waiter. Shane was very knowledgeable of everything. We will definitely be back.
