This place is hard to review. On one hand they have some of the very best Thai food in Mesa. Easy 5 stars right? Well, no. They also have some of the worst service, delivery, and a few of the rudest staff I've had to deal with in a while. 4 out of the last 5 times that I have eaten Papaya Thai I had an awful experience with their service. Really too much to explain, and I hate overly bitchy reviews, so just know that if you go here the service may get on your nerves. Otherwise the food really is amazing, only once has it been sub-par and that was after waiting almost 3 hours for delivery. It's a love/hate thing here, but good God I do love their curry. No matter how annoying the service gets, I still keep coming back so that really does say something.
Good luck.
