Caesars are my drink of choice, and I've had many far and wide across Toronto. I'm always on the look-out for a good one.
I think best caesars I've tried at a bar/restaurant/pub in Toronto have been from The Irish Embassy (Yonge & Wellington). Their Clamato is (I want to say "on tap", but I know that isn't the correct term) kept in the the same system that soda concentrates are, released from the bar sprayer. I think this makes it slightly more concentrated than Clamato from a jug - which I like. They also spice it nicely, and put the BEST topper in it - pickled beans (very tasty).
Can anyone else vouch for a place that makes a great caesar? I'd like to visit some recommended places and put them to the test.
