I have never, ever, considered PE for a meal; don't equate pizza with gluten-free. However, while browsing for last-minute Christmas shopping we glanced at the menu which shows clearly that they do cater for us awkward types.
The 4 Seasons pizza was a treat. I took half home, in a box, labelled by a lovely member of staff as GF!
The best thing though was the staff. All 3 we came across were so helpful, well-trained and professional. I hope they get to see this review.
