Serves gluten-free batter before 8pm, which is unusual for Gloucester fish and chips places. Was unable to order, as there was a miscommunication at the restaurant, that ended with an order for standard gluten batter.
Bloke on the phone was a got rude about it all, and I ended up having to pay 50% to Just Eat in order to cancel. Can't recommend - Seymour Fryer does gluten-free batter if that's what you're looking for.
