Take in some culture, there's plenty of places to visit such as Rijksmuseum, Van Gogh Museum, Rembrtandt House Museum, Anne Frank Museum (if you fancy waiting in a mile long queue to see a cupboard), Sex Museum, Prostitute Museum.
Lots of venues for gig's, The Melkweg and Paradiso are world famous.
Take in a canal trip (I'm sure you guys would love it
)
Take a piss in one of the outside, exposed to nature toilets around the RLD (do NOT take a dump there though).
If you do visit one of the cabins in the RLD, take note on what colour the lights are, you may get a bit more that you bargained for if it isn't red.
Eatery wise, there are plenty of Argentinian Steak Houses and fast food joint spread across the whole city, however I would thoroughly recommend the following at least once:
A cone of Chips & Mayonnaise.
Shoarma with hot sauce.
Noodles from Wok to Wok.
And definitely...
Churos with chocolate sauce from the little cake shop and gfast food place on the Damstraat across from The Doria.
If you don;t fancy a shmoke or space cake, then The Greenhouse has a Volcano Vaporiser, but you may have to wait in line to use it as it can be popular.
Anything else you wanna know, just ask
Where are you staying?
