I found this cafe thanks to Google reviews, and what a find it was!
They had tons of things for breakfast or brunch and a huge variety of gluten-free options (panini, baguettes, toast... And you could choose what to put on them from ingredients listed on another board). I had a DELICIOUS bacon and cheese panini, an especially creamy flat white with soy milk, and a slice of (gluten-free!) apricot cake that I couldn't finish because I was so full, but they gave me a takeaway.
The atmosphere was excellent. Almost everyone who came in while I was there clearly knew the owners and frequented the place often. I think that's one of the best things you can say about a place.
What a shame I don't live in Norwich to go there more often!
