Last year, Pop's will not accept credit cards. They had an ATM located in the Dining room. I went to use the ATM and it was empty! It was pretty embarrassing, as I had ordered a lot of food for me and my daughter's family. Since I came by boat, driving to the nearest bank was not an option. I had to wait until the owner or manager came to the restuarant to fill the ATM. Meanwhile the food got cold.
So make sure you bring plenty of cash.
