Installed on the upper floors of certain respectable taverns in Lisbon can be found a small number of restaurants or eating places, which have the stolid, homely look of those restaurants you see in towns that lack even a train station. Among the clientele of such places, which are rarely busy except on Sundays, one is as likely to encounter the eccentric as the nondescript, to find people who are but a series of marginal notes in the book of life.
