I love Nando's!
A lot of their menu is gluten free. It's a chain (multiple locations in the Us and a few in Canada) so the allergen list online is pretty detailed. I've eaten here dozens of times (at various locations) and I've never had an issue!
Pretty sure a lot of their menu is naturally gluten free. I honestly get the same thing every time ( Peri Peri bowl is 100/10).
