Espresso Tonics

Recently gave the Hibiscus Espresso Tonic at Slo on Fraser street a try and it was incredible. Since then I've had an espresso tonic at Modus on Broadway as well, which I enjoyed thoroughly. I think it's my new iced coffee drink.

Now I'm on the hunt for other spots that serve them or do interesting variations of it. In my basic research I've found reference to espresso tonics in Vancouver, but mostly where people say "plenty of coffee shops do an espresso tonic in Vancouver".

Can anybody get specific and shout out their favorites across the city?
