What to eat: It all is really good. You will find great coffee(espresso here in the states) everywhere, so it is difficult to actually not find a shop that sells coffee. When you go to a restaurant order a francesinha (steak/sausage sandwich covered in a spicy sauce); other things to ask about while you are here should include bolo de carne, chest nuts, roasted sardines, rissol. It is all good. And for your losers out there McDonald's is also here and was quite popular with the students. As for the wine, try it all; this place is a wine lover’s paradise. Dr. Basto, one of your attendings at the hospital will be more than happy to assist you in this as well as any other. Also I have informed by my residents to let everyone know that Sangrias are from Portugal and not from Spain. And the ones that I have tasted here in red and white wine are ridiculously good.
Where to go: Even with a month in Porto, there are too many things to see. But there are some things I feel you have to see before you leave. Here are a few places you have to see in my opinion
Ribeira (River): Lots a restaurants, coffee-shops wine, and great views by the river, depending on when you come, you may be able to rent a bike during the summer
Palácio Cristal/ Jardins do Palácio Cristal
Fundação Serralves : Contemporary art museum and garden, with lakes, aromatic garden, sheep, horses. It is also free with your Student ID card.
Casa de Musica: A stunning architectural fate inside and outside, with a concert style stadium inside, with an assortment of bands of different genres, from the national orchestra, the Gotan Project, to Gil Scott Heron . In hindsight, I would ask Dr. Basto about the schedule for the month you are coming. I am sure it would have been amazing to see a concert here and is one of the things I wish I got a chance to do. Free to walk around as you please, and they have guided tours everyday with one of those tours done in English
