Green House Centrum Coffeeshop

Green House Centrum is one of the Green House coffeeshops, the Amsterdam group founded by Arjan Roskam that also runs Green House Seed Company and the Strain Hunters documentaries. This branch sits on Oudezijds Voorburgwal 191, a short walk from Dam Square, and is open 09:00 to 01:00 daily according to Google.

The group's website says the first official Green House coffeeshop opened in 1992, that it now has five coffeeshops, and that it has won more than 40 High Times Cups and over 200 awards in total. Those are the company's own figures. It also lists celebrity visitors, which you will see on the walls.

Purchases follow Amsterdam's rules: 18+ with a passport or ID card, up to 5 grams per person, tourists welcome. Green House strains such as Amnesia Haze and White Widow come up in reviews, and staff are often described as able to explain the menu.

• Setting: seating inside and a small terrace facing the canal; it gets busy.
• Price: reviewers consider it a bit more expensive than average.
• Watch out: the Oudezijds Voorburgwal is inside the Wallen, one of the zones where smoking cannabis in public has been banned since 2023.

With 5,445 Google reviews averaging 4.5 (September 2026), it is among the most-reviewed coffeeshops in the city. Long-time visitors say they have come back for decades, and the main criticism is price and crowding rather than quality.
