For Thai food generally, I LOVE B&K Kitchen near First and McKinley. I know, I know, I post about it a lot, but I can't stop rhapsodizing about their fresh, bright spring rolls, the soupy, spicy vegetable curry, and their awesome service. I can't remember what the Pad Thai was like, but just today I had a different awesome noodle dish. It was made with wide noodles, oyster sauce, egg, and still-slightly-crunchy Chinese broccoli. YUM!
I would suggest Thai Royal Orchid for great Thai food in the Fresno area. I haven't had the pad thai there, but have had other dishes that were excellent. PolarBear may have had pad thai there, so search the board for his report and maybe he will have an opinion on it.
The bagel place mentioned above sounds very intriguing as well.
Frequently, pad thai is made with way too much sugar IMHO. One place that I like in Fresno is the Bagel Company (yes, bagels). It's on the SW corner of First and Nees, is only open for breakfast and lunch, and has excellent Thai food at great prices. It's small, so it can be very crowded and you wait in line to order, but the food is really good--and, every Thai dish comes with a bagel!
