Santa Maria Maior is the old core of Lisbon: the Pombaline grid of the Baixa, the castle hill, the Sé, Mouraria and much of Alfama.
It holds more restaurants than you can review in an evening, which is exactly the problem. The Baixa grid is built for passing trade. Alfama climbs into small streets and fado houses. Mouraria, one of the oldest quarters, now carries South Asian and Chinese kitchens beside Portuguese tascas.
In a district this dense, a long list is not help. Five cuisines narrowed to one is.
Expect steep streets above the Baixa. Set a smaller radius in 531 if you want to walk, not climb.
One player chooses five cuisines from what is actually mapped near Santa Maria Maior. The other keeps three. The first player picks one. 531 then commits you to a single restaurant, drawn live from open map data and Google at the moment you play. No lists to scroll, no reviews to argue over.
