People have their own reasons why they like Vietnamese pho, and why they keep coming back to their favorite pho restaurant(s.) Let’s look at some of factors that can be used to determine a “Great Pho Restaurant”
Pho Quality: is important. However, it is not always 100% true for “The more – the better”! Individuals have their own measuring stick when it comes to pho quality. It’s what makes customers keep coming back for more.

Fresh Pho Garnish. Well of course! It’s what pho is all about. It has to be fresh since who wants stale garnish? Although pho is very good by itself. many customers still prefer having fresh garnish along side their hot bowl pho. 
Pho Restaurant Cleanliness. It is important to many customers. For instant, how the restaurant look and feel play an essential role on whether or not customers come back? If the quality is great, cleanliness will always be secondary. It is especially true in the U.S.
Large portions and low (or affordable) price factors are crucial in this economic downturn. These two certainly need to go hand in hand because having one normally does not always mean having the other as well. Although comparing to other food options, Vietnamese food is already very affordable in the U.S. 
Good Service are the restaurant staffs friendly and quick in getting your order? Does your water get refilled? In general, services in Vietnamese pho restaurants still have a long way to go.
