This is my Pho restaurant of choice in AZ.
I've probably tried half the menu in the 7 years I've been a patron on Saigon Pho. Other than the regular pho choices, I'd recommend the Spicy Grilled Lemongrass Chicken, Crispy Chicken, Salt & Pepper Squid, and a host of others..
If you are in the mood for soup, but not the usual pho, order the Beef Stew Noodle Soup w/ egg noodles.
Saigo Pho has very good portions. You've probably tried your luck with other pho places and have felt short changed as the quantity of noodles in your bowl. you won't have a problem with that here.
The prices are fair.
The wait staff is always friendly and attentive. It's not like the usual Asian places where they don't ever come around and refill your glass with water.
