Friendly staff and they speak English. Small serving area, order at the counter and it is delivered to table. There is not a large menu but everything except the bread is GF. We loved the Lobster soup, grilled salmon skewer and grilled shrimp skewer. Will go back again if possible.
You must go to this place! DELICIOUS! You pick the type of fish (tastes very fresh) you want to be grilled (the menu will be on the wall), you can also order grilled veggies or a skewer of potatoes, then pick a sauce, pay, and then you can either sit at the restaurant or do takeaway. I've been here several times and had absolutely no reactions, i'm sensitive to gluten but not celiac (or at least no formal diagnosis). The staff are so kind as well, I highly recommend this place!
The lobster soup is as good as it sounds. Also naturally made GF and DF. Wish they had some GF bread to go with it, though.
