Service Dog Denied Service

I am not sure who to reach out to about this, but it infuriates me that the local dog park, Canine Cove, is totally inaccessible to a handicapped individual. I am a 38-year-old female in a power wheelchair, seasonalresident of Marco Island since 2013. I learned the hard way years ago that I would have to find a different dog park to exercise my service dog. I was with my mom one afternoon inside the Canine Cove dog park when my wheelchair got stuck in the dirt. It was like quicksand, and the more I tried, the more it sank in. My mom quickly reacted, as did everyone else in the park who saw what was happening! It was truly a team effort and using a two-by-four wood plank and a shovel, they were able to free me from the sinkhole.    
It just makes me so mad that a place likeMarco Island, that has a large majority of residents with mobility issues, would not have a park that was more inclusive! 
The reason why I am bringing this matter up now is because last Saturday, I went to dinner at Café Verona inside Verona Walk. The owner would not allow my service dog in his restaurant. He approached our table after we ordered our food and angrily demanded that my service dog leave his restaurant immediately.  
I am not going to be quiet anymore. This is wrong and someone needs to say something! 
Can you help me?
