The small bowl is quite large, so if you're not super hungry, the small will be fine and you'll have leftovers. Best Pho I've had!
Get the spring rolls to start. For main coarse, get the pho dac biet, pho chicken or pork chops with eggs over easy!
Think Chipotle ordering style but Vietnamese pho. In terms of quality, they keep it authentic and open up a variety of ingredients and sauces for a fair price. Give it a shot, I recommend it.
