Noodles and Company

We've been there for a couple of times already. Food always good. But one thing still confused me. The first time that we ordered the small Spicy Korean beef noodles had some beefs with it. But the second and third time they said I need to pay extra for the beef. And then just few days ago, we went there again and ordered the same small spicy Korean beef noodles, and they didn't ask me if I would like beef or not. And he just gave us the beef without paying extra. So I don't know if I got lucky or what. But anyways, food always great, will be back soon!!
