Have you checked into zoning issues ? Licenses ? Insurance ?
From your description, you may have already seen the good money out of the area. Or changes in the weather may effect your business. Nice weather, too much free stuff to do outside.
Alcohol isn't always the answer. They just don't hand out licenses anywhere. And cost is huge, along with setting up a good bar and increased insurance costs. Any of your group want to wrestle drunks ? Alcohol can be good and bad, it isn't a guarantee of success. Bars go broke too.
I wish you every success. Learn as much as you can. Experiment with what you have too.
