Fish and Chips is misleading. battering the fish in rice flour or grilling it, doesnt detract from the fact that most fish and chipperies cook their normally battered/crumbed products in the same oil, making the oil contaminated, and the fact that their is a lot of bread around in a very busy environment. If you are super sensistive, i would be very careful, even if they have a dedicated chip fryer. Nandos do not fry anything breaded, so their Chips are a GF winner
