So just for clarity sake, and this is just semantics, but they every fried food item that they have is gluten free. So yes they have a dedicated fryer; but even better, they have no other fryers so they can't mistakenly use the wrong one. Fish and chips were great (although a touch pricey at $21)! They also have a back roof deck which is nice and not obvious if you've never been. Old Orchard Beach is great for me as a Celiac.
Prior to going, I had messaged the restaurant on FB to verify that this has a dedicated fryer and also they answered my questions well. The waitress was helpful and knowledgeable, but when we ordered our food, my son with Celiac found noodles in the coleslaw. :( It was the proximity of the coleslaw to something with pasta. We agreed to go to this pricier restaurant thinking we would be safe, but then this happened. No offer to not charge us, just an offer for a different bowl of coleslaw. The rest of the food was already contaminated and he had been eating it. We loved the food, but very sad that we had trusted it to be safe.
I was very excited and pleased to find out that I could finally have fried seafood again. I was diagnosed with Celiac 4 years ago and since then finding certain gf foods can be discouraging. The Shack has a dedicated fryer for gluten free items. I had wings and fried clams and I was in heaven. I thanked the owner for offering fried seafood. I did not get sick. Their current menu doesn't state anything is gluten free but I believe they will be changing that.
