Scrap Metal Furniture

[Apache]

First of all, your avatar is a great album I want to go listen to. Second of all, I've always loved the Bob Dylan line you have in your signature. 

Anyway, on to the poem! 

The secret patio
behind Sanagan’s Meat Locker
smelt like fresh cut pine,
and the greenhouse bistro I don't really know what this means, but I really like it. 
beside the neighbourhood bridal boutique I think this line would work better either without "neighborhood" or with a shorter word in its place. 
bustled with hard-to-find streetwear, Don't think you need this comma here. Especially since you separate the first three lines from the next with a comma. The comma here makes me feel like the retro-inspired staples are disconnected from the streetwear, but my impression is that you are saying the store sells both. 
and retro-inspired staples. 

Across the street, local moms
dedicated to the Japanese otona trend The word "dedicated" seems to me to be a bit awkward here. I think "devoted" would sound better, giving you a little assonance with "otona". I'd consider removing "Japanese" too, because I think otona speaks for itself. It's not like there's a Portuguese otona that people will think of instead when they read this. 
bought unisex shades and muted fabrics
at Daub and Design, while a man in a tuque I had to google tuque. Had no idea that was the word for that type of cap. So now I'm happy I have a new word to use!
smoked pristine status accessories
outside the trendy cafe-slash-menswear-shop I like writing out slash there instead of using a slash, even though it makes the line a bit long. 
on Ossington.

All in all, I rather like it. I feel like it might be missing something, maybe another stanza or another line somewhere to make it a bit more meaningful to people that haven't read that magazine that you have. But I really like what you have so far, it feels to me like a nice little light parody of the sort of trendy hipster-yuppie aesthetic that's become so popular these days in many cities.
