"Delicious food" is the first thing I will say. It probably helps that they have noodles as their main dish, but the noodles that they serve you are nigh perfect. I specifically recommend the Japanese Pan Noodles (without the marinated steak though). My noodles were served with a bit of cilantro (for breath-neutralization, I assume) and the iced tea is awesome. Just don't get the sweet tea. Seriously, the market for sugar must have had a noticeable increase the day Noodles & Company brought out their sweetened iced tea.
The atmosphere is very modern. It makes me think of IKEA mixed with Asian minimalism. And I mean that as a compliment, not a criticism. Lunch is pretty noisy, but go in the late afternoon and you will be able to eat in solace.
All and all, if you are looking for a good noodle restaurant but don't want the "divey" feel of LuLu's Noodles (or you *do* want the clean feeling of a modern restaurant), I would definitely recommend Noodles & Company
