This was the first pho joint I went to, many years ago, so it has a special place in my heart.
Went back recently for the first time in ages, and I do have to agree with what LiveToEat says below: the soup base for my pho bo ga (i.e. pho with chicken and beef) was underwhelming, or at least not what it used to be.
A word of warning, as well: Pho Bo Ga are indeed all about the pho. Those who aren't into pho will have to content themselves with the one dry dish on the menu.
Here is the fabled "Special A" (large). Satay style soup with beef, shrimp, and BBQ pork. Lightly spicy, and graced with slices of tomato and shredded Nappa-style cabbage.
