We've come here several times for lunch, as it's close to work. It's mediocre. I'm a vegetarian and they don't have a ton of options -- they have the usual stir fry veggies, veggie lo mein, veggie fried rice. I opt for the crispy tofu and veggies with brown rice.
I'd suggest to STAY AWAY FROM THE TEA. Their iced tea is gross, and probably a Nestee product. They don't brew it, and if they do, I don't know what kind of crap they use. My only gripe with Flo's.
Overall, it's an average experience with Chinese food -- for an average lunch price ($8-11)
