Jump on a ferry and head over to Victoria, I got properly pissed on just 4 pints of locally brewed island beer
Thing is, I can't quite remember exactly where I went....
But Victoria is somewhat smaller than Vancouver, so pub crawling/staggering is fairly easy.
It's also a very nice and scenic 90min trip on the ferry. You can take a bus from central Vancouver to central Victoria which will include the ferry ticket.
