Any bars that offer open mic nights?

Hi,

I used to live in Tampa and the local bar scene was more vibrant - some places had open mic night where they would bring out instruments and anyone can come up and play/sing along.

I am missing a little of that and maybe i have not been looking at places but wondering if there are places down here in south florida that do that? I live in hollywood but can drive anywhere north/south.

Cheers
