This place is a hole-in-the-wall and you'll come out of this place sticky/humid with all your clothes reeking of pho and fish sauce, but you'll also come out totally satisfied.
While their prices are slightly higher than China town, I find the food much better. Portions are decently sized and the broth is delicious. I love the spicy broth add-on, which has a tomato/lemongrass taste to it.
This place is always packed but tables turn over quickly, so you won't be waiting too long.
