Easy 5 star. One of my favorite places on earth. This is, hands down, the best Pho I have ever had in my life.
The best broth is the one that is the most transluscent. It should almost look like water. This is that type of broth. It packs so much flavor its incredible. It's fresh, flavorful, and is so satisfying. Just the smells alone are worth the price.
Go here, and don't stop coming back.
