I have no idea what street dances are, but dance is pretty rare in anime.

Street dance is like Popping and associated (waving, tutting, ticking, botting, strobing) , Locking, Street Jazz, Bboy (commonly known as break dance), housing, hip-hop. It actually really surprises me, that dance is pretty rare. Japan is the largest dance center outside of the U.S. in the world, and half the best dancers in these styles are from japan. Not to mention some of the largest dance competitions take place in Japan. It boggles my mind that they have manga about american foot ball, but nothing about street dance.

I'm guessing you mean something like K-On except with a dance club instead?

I've never seen K-On. So I wouldn't know. I guess anything that centers around a modern popular dance style.
