This trendy, design-forward, evolution-themed cafe suffers from a bit of scholarly overreach inside (though the big, round banquettes are great for groups), but its elevated terrace affords postcard-perfect views of the Rio Tejo and Torre de Belém. It draws a fashion-forward local crowd with sophisticated pastas, risottos and the like, as well as an extensive list of bubbly by the flute.
It's a bit hidden away inside the state-of-the-art Champalimaud Centre for the Unknown, just west of Torré de Belém.
