Forgot to mention - Just the Tonic are also doing FREE comedy nights (if you book online), in the form of auditions for their Big Value Comedy Shows. Comedy wanabees can come along to these shows and compete for a place in one of the Edinburgh Festival Big Value shows. Obviously not all the comics will be great, but it's free and you might get to see a star of the future!
The next one's Wednesday 21st March. To book your free seat, visit http://www.justthetonic.com/Leicester-comedy/shows/wednesday-21-mar-2012/681/
Note: By the way, I'm not in any way working for, or sponsored by, Just the Tonic. I'm just an excited comedy fan. I will be mentioning many other venues as the blog develops. That is all.
