Well we should probably wait till the end of 2011 for that but...
Have you noticed that there just aren't that many nightclubs anymore to begin with? Let alone good ones. The City has placed so many restrictions on them that only a raving lunatic would open one now. (Although, come to think of it, there always was a bit of the raving lunatic in every club owner...)
And it does seem that nightclubs are happy (and lucky) to have just one "hot" night, forget about 7. Of course the definition of what makes a night "hot" vary.
But, what is your "best" nightclub of 2011, saxe83?
