My go-to is Combination Pho. I wouldn't call my self pho connoisseur until the day I try all pho in Vegas, but out of all the ones I've tried, this one has the most flavorful broth. And theirs is the least salty in my opinion. Garnishes are kept simple but always fresh (no wilted bean sprouts and basil here). And service is very fast! They wouldn't be the most friendly servers, on the surface. But once you start asking questions, they are actually quite personable :)
