Thing is with Basjoe, the budtender James is SUCH a cool guy that it really is worth going there to have a chill-chat with him. Heaven's Haze is pretty good there if they still have it (4 months ago I was there) and Bleak's pics of the current Bas Special batch look pretty good too. Last time I was there he gifted me a PHAT joint's worth of his 'private stash' which sent me into orbit despite having just smoked 2 big H.Haze Js. Definitely a man to know and he's real easy to chat to.
The STANDOUT places for weed quality are, imho, Voyagers, Grey Area, Barney's but almost all shops are worth a look-in as long as you dont mind saying a polite No Thanks if you dont see what you like. 420 De Kuil and Hunters are usually ace for a bit of Super Silver Haze and NYCD respectively. Anyday is a brilliant place for unexpectedly good town centre stash, too!
Have an awesome trip!
