My rental vehicle was broken into while park at a local denny's in south Florida. I may have a case for restaurant negligence. do I have a case?

On Monday morning my friends and I stopped at a local Denny's for breakfast. When we finished and walked back to our rental vehicle, we noticed the vehicle was broken into as all our small bags were stolen. One of the Denny's employees (our server actually), almost immediately came out telling us that " oh no, you guys got broken into, this happens here all the time, there are no cameras, police does nothing" etc. We called 911 and police arrived to take our reports. The police officer also stated that "items would be hard to recover and that this Denny's and the IHOP across the street are a regular target for these types of crime. So, if the police knows that this is a target area and so does the restaurant, why no one does anything to help protect the visitors. Denny's could install security cameras which could deter potential crime and so could the city or police.
