Yeah, I like Escape the best - but it's completely across town for me, and I use trimet -- so I hardly ever get out there.
I went to Elements on 34th and Hawthorn today (didn't count the 5/6 people in there as "vapers in the wild"), it's a lot smaller...younger umm Hawthorny vibe to it...but it's cool, they have a tasting bar w/a decent selection selection of mods/tanks. They didn't have visible prices though and I didn't ask, just wanted to check out their juice bar -- Five Pawns, Suicide Bunny, Bryce's, Neckbeard, plus several I'd never heard of and can't remember now, but were decent.
There's one above Voodoo downtown I've been meaning to check out...but haven't made it in. I hear it's full of ultra hipsters.
Also one around 50th and Division, I've heard good things about.
