It's true they only take cash but it has always been a cash place even when I was young. The food is good, the people are friendly, and can't beat the location. If you need it, there's an ATM close.
Had a good breakfast for a fair price. What sets The Hole In The Wall above other restaurants is the cheerful waitstaff. Must try dinner next, prime rub on Friday.
I had breakfast here with the family when my son was getting married at a local church. We ate upstairs on one of the coldest weekends on record. All 6 of the company enjoyed what we ordered.
