The food is superb, the restaurant is tastefully decorated and clean (and I've never had bad service there), and I love supporting a small business in a city overrun by chains and franchises. That being said, I've been scolded twice for ordering delivery outside of their delivery zone. It's really irritating when you drop $40 on a meal plus generous tip and are made to feel like you inconvenienced the business. If you don't want to deliver to certain addresses, then feel free to turn down that order when it's phoned in. What's ridiculous is that I live in Surprise proper, it's not like I'm outside city limits.
That complaint aside, this is the best place to get thai on the west side by far- hence the 4 star rating. Just don't order delivery unless you're within the tiny 3 mile delivery radius.
