I wouldn't normally review a Tim Horton's (what's to review?) but this Yonge and Eglinton location recently introduced Cold Stone Creamery to the store. Tim Horton's has partnered with Cold Stone Creamery to do this in several of their locations.
Since everyone knows what Tim Horton's serves (cheap bad coffee and sub-par baked goods), I went here to evaluate the ice cream. Cold Stone Creamery specializes in serving their own ice cream, but you get to choose your "mix-ins" which they mix in to the ice cream on a cold slab. I opted to go with something simple - the smallest size of peanut butter ice cream - no mix-ins. It was pretty good - not the richest most flavourful peanut butter ice cream that I've ever had - but tasty and enjoyable none the less. The serving size is quite large for the smallest size in my opinion. I believe my ice cream was $3 plus tax.
Their menu displays a bunch of "Signature Creations" such as (continuing on the peanut butter theme) Peanut Butter Cup Perfection (chocolate ice cream, peanut butter, reese peanut butter cups, and chocolate sauce, served in a waffle bowl). Yikes - I would like to try this but only if I have someone to share it with. It's clear that this place is loading on the calories, even for an ice cream shop. As a matter of fact, Cold Stone "won" an "award" from Men's Health magazine recently. One of their milkshakes was named the most unhealthy drink in the US (The PB&C milkshare, which has 2000 calories and 68 grams of saturated fat, the equivalent of 68 strips of bacon).
