I love this place. I first discovered it with coworkers when looking for a lunch place last summer, and have been hooked ever since.
I always get the tofu pho with chicken broth, and it's sooo good. The portions are pretty big, too, so I always feel like I'm getting my money's worth.
The noodles used in the pho are rice based, which is (partially) what drew me in to begin with, and even better some of their spring rolls are made with rice paper so I can eat those, too. You wouldn't believe how many "traditional" Vietnamese or Thai food places in the city don't use rice noodles, so I love that a place near me does.
My only complaint is the hours: they strictly cater to the business crowd, so operate 11-5 M-Th and close at 4 (or earlier!) on Fridays. Not open on weekends - a total bummer when I have a hankering for pho on a Saturday!
