Far from the Nandos peri-peri (which is delicious in its own right) is the Portuguese charcoal chicken and periperi oil. I'd tried it twice in Lisbon before (https://eatlikeushi.posthaven.com/o-churrasco-lisbon-10-2013 and https://eatlikeushi.posthaven.com/bonjardim-lisbon-05-2019). Each time I enjoyed the roast chicken noting the chilli (but not savoury) addition of chilli oil although not thinking it was a particularly special meal to set out for.
With one week in Porto, meal variety was important and why not a nice roast chicken? It was difficult to find consistent recommendations but Pedro Dos Frangos was a longterm institution, so popular they had opened a second one across the road. Watching the chickens being rotated slowly over the coals was a beautiful sight.
Far from the more expensive Lisbon prices (€10.5 for a whole in 2013, or €7.6 for a half in 2019), a whole chicken with fries cost a mere €10.5. It came with a semi crisp skin, not seasoned but with a touch of salt and peri oil it was delicious and great. Not the most tender but adequate (I suppose they just keep roasting until they are ordered). Chips were pretty good but not that crisp. A nice simple salad accompanied.
If it was only a short visit to Portugal, I probably would stick to seafood. However any meat cravings could easily be satisfied by a chicken.
