I've only been during "The Big Taste", so my experience may not represent a normal night at Blink.
We liked the decor- simple, modern and sleek, but still warm. We were seated near the back with a view of the (bright) kitchen and the bar. We noticed a cute-looking booth at the front with a great view of the street outside- worth reserving for a small group in the future!
For dinner I ordered from the Big Taste menu. My starter was a salad of endive, pears, parmesan and walnut. It was delicious. My entree was the ricotta gnocchi (with black chanterelles); it was also very good, but not a filling portion. I don't know if they serve a larger portion outside the Big Taste season. Dessert was an ice cream sandwich with homemade ginger cookies and caramel ice cream- again, really good.
Overall service was friendly and attentive, although after our meal while I was in the washroom my friend overheard the staff complaining about getting a small tip from another table. Definitely unprofessional. Another small complaint is that similar to other 8th Ave restaurants the basement washrooms smell a bit like sewers. I know it's (probably) not their fault, but if I'd been paying full price for that meal I'd be expecting top food, service AND facilities.
