Basically there are soooo much things you could do here, I will share what I did there. Here are several things I believe you should try:
- take a boat tour Well it basically cost you around 12€. But please don't go there directly to buy, perhaps you should ask if they have a package with the wine tasting. I was a little upset when I knew that if I bought the boat ticket, I could go to the Ferreira winery, for free. The thing is, I went to Ferreira first and then I took the boat tour. I told them that I paid for the tour and the boat lady gave me a discount (They don't even ask my ticket/receipt, maybe you should try it to get a discount-- if you know what I mean). So, I paid for 9€ and go directly to the boat
It goes under the bridge and the other places around. There's some like tape recorded tour played on board but you won't really hear that because of the amazing views. And probably the boat is full of people.
- Wine tasting, wine tour, wine cellars... Wine, wine and wine Caves Ferreira, Caves Croft, Espaço Porto Cruz, Caves Calem and the others. You name it. There are so many wine cellars, and of course wine shop. Try the very famous Port wine. They are unbelievably sweet, with higher alcohol (careful not to over indulge it).
It was cheap, there are four famous type of Port Wines: white wine, and three red wines: Tawny, Rosé and Ruby.
Some parts of the city you can even taste green wine. You should ask from the locals to get one.
If you wanna bought one for souvenir I would suggest you to buy it here. Hence, don't worry too much because at the airport you could buy some Port wine in the duty free. Enjoy it while it lasts, the best Port wine you can get is in Porto (duh, obviously)
Maybe all the thing you know about Porto is just about the Port Wine... Or maybe you don't, you know nothing. Well Porto, or Oporto, is the second largest city in Portugal after it's capital. Beside the wineries, you can see beautiful buildings and outstanding transportation (I'm talking about how clean the metro is!), there are so many things you should do while you're in the city elected The Best European Destinantion in 2014
Try the famous Francesinha in Café Santiago
Open from Monday to Saturday, that's enough to make your tummy satisfied with the signature Porto dish, Francesinha, which literally mean french lady. Well, to be honest with you, after eating that I don't feel like a lady at all! The portion is really big and there are several types of Francesinha, but I suggest you to go with the special one. Or you could go ask the waiter, don't worry because they speak english very well.
It's not that expensive, well it is for a Francesinha, but this café won several awards throughout the years. It will cost you around 7-10€. I personally recommend you to go in weekdays probably around 2pm, because once I went there around 7pm and I could see the long queue outside the café. Just to remind you that your stomach should be empty, because like seriously, this thing is huge!
I also ordered a vegetable soup, it is a typical Portuguese dish. I found many locals eat the soup, it's a bit creamy with many veggies inside, it costs only around 1,20€. Be careful when you order things, because like I said before, the portion is really big, it could make you feel a bit bloated. I also ordered the house wine, it's a green wine. I was a bit confused at first but then I soon found out that that's a typical wine in Porto.
