For me...
Paradox
Had some great times in here over the years, very friendly staff, great little smoke menu, good food and drink. I'd get a nice couple of grams of BioGreen or NY Chiesel, a Banana milkshake and a veggie burger and spend a couple of hours reading. Bliss.
Stix (Korte Koningsstraat)
Love it in here, area is really nice. Had some of my best smokes here, never had a bad deal in many years. Lovely people too, always a bit eclectic/eccentric, always very helpful. I'd be having a gram of White Chocolate and a cappuccino to kick start the day!
Het Ballontje
Love the 'feel' of this place because it's not in the main centrum and never gets too crowded. A nice lemon tea with some White Balloon would go down a treat!
Honourable mentions go to Bluebird, Kashmir Lounge, Greenhouse Tolstraat, La Tertulia, and De Graal.
Bit of fun amongst a mountain of gloom eh?
