I work at NYU and have been eating here for lunch a lot lately, perhaps because I've gotten bored with the usual choices. I keep ordering the Soon Du Bu, which doesn't have zucchini and has a somewhat thin-tasting broth, but which is also fresh-tasting and fairly spicy, with perfectly tender seafood (even the calamari is tender!) and buttery soft, strikingly delicious tofu.
If you just think of it as a spicy seafood soup with some fine tofu, it's really quite nice. Their rice is not really the greatest, but dunked in the soup is fine.
The Bi Bim Bap, again, looks fresh and tasty, but no fried egg. So if you order it thinking of it as just a nice vegetable and beef medley over rice with chili sauce, I'm sure it's good.
The salads also look quite good and they serve pajun. This is not destination dining, but if you work near the corner of Mercer and Waverly, it's definitely a lunch to add into the rotation.
