The time dedicated to the explanation of the history and processing of diamonds is very small. More than a tour it looked like a promotional sale. Nevertheless it was overall a good experience, as it gave some info about diamond quality and times of production.

Gassan Diamonds is one of the Hop On Hop Off boat/bus trips in Amsterdam. Free entry. Staff friendly. Worth hopping off the boat. Definitely worth a stop if you're thinking of proposing!

Amsterdam’s buzzing hub, with its sprawling network of
tram rails and a seemingly constant flow of tourists
and commuters, yields convenient access to some of the
best sightseeing, shopping, and street life in Europe.
Closest at hand are the Royal Palace, the quaint shops
of Haalremmerdijk, the pedestrianized zones
Kalverstraat and Dam Square with popular neighborhoods
such as the Red Light District, and the Canal Ring

Dear Alex, I have read your question but I have no answer as what I have reviewed is about Gassan Diamonds and not Restaurant.
