Finding Fun Food

Candle light dinner last night! Patricio prepared some great dishes, and he doesn't even have a stove anymore, cos he'll be moving soon. After that, as per usual, I stayed in the flat reading, and he went partying. (He was verrry tired this morning.)
Today I finally managed to visit the spectacular Casa da Musica (see picture) and the Museum of Modern Arts, Fondacao de Serralves, and I strolled around Porto and Matosinhos for hours on end. Ever so often I stopped in a cafe for a coffee (and a cake) or some petiscos.
So I enjoyed one of my favourite games some more, "Finding fun food". This is the way I do it:
First of all you make sure it's a small place and crowded with neighbours. It's very important not to do this in a tourist restaurant!
Then there are different ways to go on playing:
a) You look up the specialities of the house and order one of them. You never read the name before, you got no idea what it might be made of, what it might taste like, but you order it anyway. Like today, it was papas thingy. It looked like a soup, had a flavour of liver, and might have been anything. Was very nice, though.
b) You ask for tapas, or, in Portugal, for petiscos. And let the waiter or the cook decide what you'll get. I had the strangest dishes you can imagine, like meat and clam soup in one bowl, and in the second some tripas (I think).
c) You have a close look onto the food on the bar and choose the first to the right. Or the second from left, according to what you decided b e f o r e seeing the food.
d)You order the same dishes your neighbours at the next table are eating. Not that much fun, to me.
e) Sometimes you find a bill on the table from people that ate there before you. Just choose one ore two of the dishes they had. This always works nicely!
I only had a slight problem once, when I ordered a coffee and a galao. I was looking forward to the great pastry I'd get, but the waiter brought - another coffee...
Two more days in Porto - I like this town so much, and Patricio loves his last guest in the old flat to stay as long as I want to. Tonight and tomorrow it's his turn to decide what we'll do. I wonder...
