I recently discovered Chinook Liquor - a small place just south of Bubbles car wash opposite the Chinook Mall, at 6008 Macleod.
A very unassuming place, it certainly does not impress from the outside - but the beer selection was wide & varied - not huge; but as many imports as domestics. When I buy beer, it's my habit to try things I've never had before - and I usually only find a couple of brands at any given place.
Here, I spent $300 on about 15 new finds (the downside is that almost everything imported, is sold in standard 6-packs, so now my beer fridge remains packed with those I didn't like so much... :<)
But - for the true afficianado, it's worth a stop while driving up/down Macleod.
