Sadly, Trebol blows. Service especially: I think I've been there with small, not-at-all-high-maintenance groups about 6 times total, and every time they found some ticky-tack thing to say no to that bummed everyone out momentarily.

Haven't been there in a year or so, even though I live nearby.

Besides, Cruzroom on Alberta holds the awesome fancy taco title currently, and it's cheaper and with better drinks to boot.
