Cidade Baixa at night is where you want to be drinking beer.
AVOYYYYD Moinhos de Vento unless you got LOADSA DOSH and / or a BMW, you won’t be allowed in with your pogo-stick or Space Hopper, and best leave the rucksack in the hostel. Oh, if yer a biker, Harleys are quite acceptable but they don’t take to kindly to oily greasy jeans. Corporate Management bikers are fine, the Hairy Arsed variety NOT, (though I believe that Corporate Managers also have Hairy Arses)
