Here is my list of my favourite restaurants in Galway that cater for Gluten Free. These are the places I've been to multiple times, that have great gluten free options and I've never had a problem with been glutened at any of them. Of course I still always mention I'm coeliac so they can take extra precautions when preparing the food. I'll continue adding to this list but for now these are the best ones :)
Hooked is located on Henry street and have great options for Coeliacs. They understand about cross contamination and use separate fryers. My favourites from here included the battered fish and chips and the spicy coated Calamari.
Greens & Co
Green & Co is always a treat, they always have loads of gluten free options on the menu and they are 100% Vegan too. Anytime I go in they usually have new stuff to try on their menu too and I've never been disappointed.
I really love McCabes Gastro pub in Salthill. I'm really lucky this is my local pub! The staff are always so friendly and well aware of gluten free. I've gotten many lovely dishes in here including steak, risotto, burger and duck.
It could be argued that Caribou have some of the best fries in Galway. They have separate fryer for the chips. There would be other breaded food in the kitchen but once you say you are coeliac they try there best to make sure there is no cross contamination.
Woooza pizza was phenomenal. I got the Margherita di Buffalo and cannot wait to try more. The base was light and crispy. When I called them they told me the gluten free pizza is cooked in a separate metal tray in the oven.
Lana has so many gluten free options. They're a Thai restaurant and take-away in Salthill and I just really love them. It is here where I had my first spice box! I usually get the Crispy Sweet Chilli Chicken with chips or a Spice Box.
Brasserie is a really nice restaurant in town. Loads of gluten free options and the food is just incredible. I usually get the Sticky Korean Style Chicken or Sea Trout on the lunch menu.
If you're looking for a really tasty gluten free burger on the west end of town, BóTOWN is great. Their staff are very knowledgable able gluten free and the chips are doing in a dedicated fryer.
