I can finally answer the question “Is there a cheap and good place in Amsterdam to try?”
Amsterdam is an expensive place to eat and live, frankly, and there are great places that are good value for what you get. But, I’ve finally found a place which is just cheap and good.
I only tried the sandwiches which are either €3 or €3,50. I also got an espresso for a meager €1! Can’t beat that anywhere in Amsterdam.
It’s just a hole-in-the-wall take away place. You can also get typical pastas and cannoli and if they are as good as they look, fantastic!
They don’t have a website and said they are moving soon (up the street) but go and enjoy it in the mean time.
