Thanks for all of the posts, I did contact a few lawyers today (including one who I went to high school with and knew me well) and they all basically said what you have said. I know it is going to be hard for me to accept the restaurant getting off scot-free but it is just something I will have to live with.
Also to the people who said that nothing illegal was done, well if it is a civil case than nothing illegal has to be done, if it caused harm to the client they can be sued (which is why I should have probably said something like file a lawsuit instead of press charges). But as you and a few lawyers told me I still don't have much of a case given that I was not physically injured in the event.
To the person who replied on my incident over a year ago, that involved drinking and a few other things so it was justified, although I should also probably mention that I was only kicked out of the indoor part and could have stayed on the outdoor part if I chose to. But I have since been welcomed back to the entire establishment, a local radio station routinely has free concerts there and I have been to at least 3 since the incident happened without any issues whatsoever.
Obviously this is not the outcome I would have liked but something I have to accept.
