This is our first trip to Lisbon. We have rented an apartment for a week at the end of March. The apartment is in Bairro Alto on Rua do Norte. We plan to eat out frequently, but would like to have on hand coffee, wine (port!), and we may wish to have dinner in a night or two. When we have traveled in the past and rented apartments, we have looked for local food markets or delis to buy cheeses, olives, sometimes roast chicken or other tasty take-away treats. Can anyone recommend any places in Bairro Alto near Rua do Norte?
