that oatmeal stout is very fine indeed. in fact all the st ambroise stuff is good. i like their pale ale as well.
i'm also really digging Hockley Dark Ale, from Hockely valley brewing. really dark colour, traditional ale taste with a chocolate aftertaste. and if i want to drink on the cheap, the least expensive can of palatable beer the lcbo has at the moment is Warsteiner, a german lager (white can, grey writing, look for it). at a $1.90/500ml can you can't go wrong. better than stella, IMHO.
