E-spot is great compared with CHQ! Many of the machines take quarters so you don't need to worry about tokens unlike at CHQ. RUSH closed a LONG time ago though!
Yes, the reviews of CHQ at Metrotown are poor mostly because the manager there is anti-social! The employees at that arcade seem normal though.
There is another CHQ at Playland though so you might want to visit that place too. There is also a Movieland Arcade in downtown Vancouver.
I think that covers all of the arcades in greater Vancouver although there may be arcade machines in a laundromat on Granville St. and a restaurant in Coquitlam.
I'll definitely play Pop'n, GFDM and IIDX at E-spot since I live in Vancouver. I'll visit CHQ at Metrotown to see if they have any new dance machines.
