Other than the Gulf to Bay World of Beer (which used to be my favorite store in the world), there's also a lot of fun to be had at the Dunedin brewery (it's on Douglas Ave just south of Main St). There's a gas station (I think a chevron) at the corner of Main St and Alt. 19 that has 101 varieties of beer... and Leuken's liquor store at Patricia and Main St. has a healthy selection at close to half the price that World of Beer charges for their brews!

Now I just need to find a place that'll ship me Molson XXX at a decent price and I'll be in heaven :)
