Height Street used to be the in thing for weed in San Fran circa 2001 
We passed by Jimi, Jerry, and Janis's houses in Haight/Ashbury while on the hop on/hop off bus. Charles Manson also stayed there...not a fan
I've visited consumption lounges in a few different countries. My tour started off in Amsterdam, where I usually end up in The Greenhouse, Jolly Joker, Bulldog, or Stones.
The coffee shop culture in Amsterdam is (in the main) geared towards the tourist industry and most premises I've frequented have been dark, sticky, noisy and unventilated. The ones I've visited in Spain (Tenerife & Lanzarote) however have been far cleaner, had decent extractor fans, and have more of a social vibe with games such as chess, draughts, cards, Jenga, Connect 4 laid out for members to play (membership €20 pa).
Dispensaries & consumption lounges/coffee shops usually go hand in hand in The Netherlands and Spain, but not so in the US. Dispensaries in Nevada opened in 2017 and the first legal lounge in Vegas (Smoke & Mirrors) opened in Feb this year, so there are only a few dotted around.
I visited Smoke & Mirrors a couple of times while in Vegas. The staff were very helpful and knew their product and it's respective properties. The premises were fresh and extremely clean, it was a joy to visit.
Similarly in San Fran', the staff and premises were excellent. My lounge of choice was the Barbary Coast.
I won't go too much into the product here, but they had dab rig's available, which I tried for the first time
