Have only been there once. I ate inside, versus on the patio. There is no bathroom for patrons.
When I asked if this was against the law, I was told, "No , that's only if we serve alcohol." Really?
So, after I ate my veggie burger and left, i just pee'd outside on the grate -- the one right in front of where the drive-up customers drive up. I waved to a few who
had braked for me after I stood up , shook off and zipped up.
