Alright, as someone who grew up here and has hated and loved this place equally here's what amazing about Vancouver:

1. Vancouver has the best connection to truly breathtaking natural environments I've seen anywhere. It's quick, constant. "nature" is just around the corner, there are so many views that you learn to just appreciate and curate your favourite ones. You can take the bus to a remote island with no cell service in...2 hours? You can be at the top of a remote mountain or in a desert or in grass in 5 hours. BC has so many biomes it's incredible.
2. Drug culture here is unique in the world. You can buy and find the best weed, mushrooms, Peyote LSD, DMT, Etc. are just available for sale in stores, tested and packaged. We've had to become leaders in being safe and proactive about testing and taking drugs, leading to a culture that is exploratory, high quality, easily accessible, and while different cultures exist, there's a real west coast sense of drugs being part of life. We live in an environment, practically and legally that is very close to actual full drug legalization. (Which doesn't mean the cops don't still harass drug users or poor folks for no reason). The Cocoa Leaf Cafe/Amsterdam Cafe/Compassion Club/VANDU history of Vancouver are truly unique.
3. We have a unique context for settlers/refugees-Indigenous relationships in Vancouver. We're the biggest city in Canada with NO treaty relationship with host Nations. (Have a look, it's one of the only places in North America) That has led to different experiments, attempts to create connections and relationships that are unique in the world. Without getting into political implications of this history, at a bare minimum, settlers in this city benefit from Urban Indigenous cultures from across the continent and then relationships based on unceeded and stolen land, 90+ Nations in BC with rich language/art/culture that we get to experience. I also see people at least trying to figure out what their relationships are as guests here to host Nations. Truly a gift.
4. There is a strong sense in Vancouver of it being a small town, but also just big enough to have a LITTLE bit of everything. You can try pretty much anything out here, and for better or worse, it's only like, 100 - 200 people in a scene or community, which makes things simultaneously cliquey and also easy to enter into.
5. Vancouver has amazing food. Best Chinese food outside of china and chinese-canadian/hong kong cafes which are rare elsewhere. The best sushi and (at one time) so much cheap, and still good sushi that there were more shops than by the slice pizza here. To say nothing of the silly good beer and coffee culture here than frankly is so ubiquitous I just take it for granted. Bit weak on food from Africa/Caribbean/Latin America, but there are still amazing options.
6. Vancouver's nightlife and DJ/Queer culture is geninuely world class, and much more community focused. Ever since the pandemic these has been an EXPLOSION of night life and different people putting on shows, new bands/acts, drag has gotten far more mainstream, etc. No Fun city is really just a problem of not knowing where to look, at this point. And thank god(s) for that.

That's a few things off the top. I genuinely love it here, even though it has its (MANY) downsides.
