It was a posh fancy restaurant.
We ordered this dish, which was a Catalunian specialty, something with 4 cheeses and tuna.
Seafood paella. Not bad though, like 3/5.
The total for the bill was €160, and it was €40 per person.
Yes it was only the 4 of us, and we couldn't finish 1/2 of it. It was such a pity and waste. Next time, we shall only order what we can eat and not be a glutton.
