University Reputations for Physics

What universities are considered to have good physics departments? Especially in the quality of undergraduate teaching?

I have a few unis which I tend to think of, but I have absolutely no idea why, so if someone could give me a better list that would be great.

I found a league table for you.

But also, i know people that went to uni "down in the 20s" and are now doing PhDs at Oxford/Cambridge so i don't think it really matters.

Sorry for the late reply, thanks for this! I know your uni doesn't make a massive difference, but I may as well start by looking at unis which are supposedly better (then if I don't like them start looking at others obviously )
