Crowded on a Thursday night, but not really worth the wait. We had fun, and the bar is decent, but the service was average (which for Vegas is code for "not great") and the food is fair. A few good tapas (I particularly liked the crispy duck egg-roll thing), most were only OK and not that special. Lots of Asian-fusion tapas, which sounds like it would be good, but it wasn't really (except the duck thing). I much would have preferred amazing Spanish dishes.
I also was a little surprised that the inside was almost exactly the same as the old Z Tejas, just a new paint job. I never liked the step-down dining room and I think a complete renovation of the space would have been better.
Quite frankly, the reason it was so crowded is because there's a dearth of places like it in or near Summerlin. Which made it fun to go to, but I'm not rushing back anytime soon.
