What does 'no corkage allowed' mean?

I imagine that if they weren't going to charge corkage it would say "no corkage fee" or similar. I think that means that you can;'t bring your own alcohol in.

I would assume it means you can't use your own wine / fizz. If it was for no charge then I would have expected them to say no corkage fee rather than no corkage allowed.

Ah ok thanks for replies :-)
