I have driven by this place numerous time but didn't give it a second look solely based on the structure. From the outside it looks a little questionable. But when I did a "best of Thai food in 85040" search on yep it come up with over 400 great reviews. I don't usually take time to write reviews, but for Chanpen Thai Cuisine I will!!! It is a small place, don't plan on eating there if you arrive after 11:15 AM. My favorite dish is the Pad Thai. Food is always fresh and large portions. They even have creative daily specials. Staff is friendly and I have always had great service. When you order take out, they give you a bottle of ice cold water no charge. A hidden gem that you must not over look.
