If you can only visit Pho Real just once, then you must order either the Hanoi Beef Pho or the Hue Spicy Beef Noodle. I have not tried the Dry-Style Beef Noodle but I trust that it is good too.
I tried the Hue Spicy Beef Brisket Noodle (with add on tendon). Ooh! Very nice! The broth was sourish and spicy.Very appetizing indeed.
