My old workplace used to be close by here, so we'd drop by whenever we had a hankering for Vietnamese. I like that this place is quick and easy so you can still enjoy lunch in a reasonable time.
I've tried noodle dishes (anything with shrimp is a definite yes), but I always go back to their pho sate. They bring you plate of fresh herbs along with your heaping bowl of soup (which I can never finish but want to!). The spice is not too overpowering and the broth is great.
Reasonable prices and convenience are also factors of why my former coworkers still continue to go here.
