Boy oh boy so I love Costco. I think it's the "exclusivity" of needing a card to get in..I try to make friends with the folks that have one and use them to my full advantage :D
The Costco at Elgin Mills and 404 is great, it's really big, relatively new and it's always got yummy samples!
Samples are my favorite - especially along the deli and cheese isle. I like going there semi-hungry on a Saturday or Sunday and trying everything while swearing that I will come back to buy!
They have a great grocery section here, as well as A LOT of trendy books and cheap packages of socks! I've been to a few Costcos, haven't met one I didn't like really - most of the stuff is similar throughout. This one has my favorite sweet of the moment - a huge tray of baklava with pistachios in really fluffy layered pastry. It's cut up into smaller size pieces so you don't feel too guilty.... I just eat half a tray in one sitting but hey, whatever floats your diabetes!
