Cheap. Large portions. Fast. Yummy I paid $7 for a giant giant plate of tasty noodles with tamarind tofu and greens. Order at the counter, get your number, and your food will arrive at your table in 5 or so minutes.
In the summer they have rolling garage doors on two sides, which makes this almost like a patio and a very nice place to spend 20 minutes snarfing down some noodles.
