I'm a big fan of Ph Thành Restaurant at 17th Avenue and Camelback Rd. I've tried several different restaurants that serve Pho in the west valley, but most of them were "meh" until I tried the Pho House. Very similar tasting Pho and I'm a fan. I visit them several times a month and it's great because it's much closer to where I live. Staff are very nice and courteous. Sometimes they can become a little overwhelmed during peak times, but not a major issue for me. If you like chili oil, they have it; it's not on the table, just ask for it.
