As names for cocktail bars go, Proof is pretty apropos — but luckily for the imbibers at this King St. establishment, it far more than a clever name. It starts with the craft cocktails, made from premium ingredients, and moves on to the extensive list of wines by the glass and more than reasonable beer list. A chalkboard menu of bar snacks like boiled peanuts and meatballs keeps your tummy full, which is a good thing — with the relaxed upscale atmosphere, you're likely to stay a while.
