Lotus of HOTDAMN!! Easily hands down the best Thai food I've ever had in my life. Haven't been to Thailand yet so we'll see when I get there. But jeeeez... everything is more than reasonable and affordable. Only con about this spot is that reservations are difficult to get. And walk ins are usually a long wait. Plan ahead of your trip and make that reservation early, it's worth it.
My top 2 are of course the crispy duck curry, it has coconut taste in it and I usually don't like coconut, but I ended up drinking the whole curry with the duck. The garlic prawn or garlic shrimp is fried to perfection. Eat the whole thing from head to toe and love it. I think I'll be coming here every Vegas trip now!
