We had an overall good experience at Johnny's. Our server was knowledgeable about what is, or could be made, GF. Note, we were told (when we specifically asked), that they DO NOT have a dedicated GF fryer. I don't know if that means they really do not have a second fryer period, or if the GF fryer is at risk for cross contamination, as someone else mentioned. (Our server was aware that we had celiacs in our party). Offered GF buns for all sandwiches (though nothing special). It seemed that our three celiacs all felt OK after this meal; I suspect it can be celiac safe if you ask your questions and feel comfortable with the server and his/her answers.
