Thanks!Regarding grades, that's a tough one we've takled about a rating system, but at this stage decided against it for 3 reasons:*There may be restaurants that we only try once, and it's not really fair to give a grade based upon a single experience.*Some of the restaurants may be excellent at a few dishes, but overall so-so (or vice versa).*We recognize that our opinions should only be taken so seriously. We love that people respect us enough to seek rating information, but we're not entirely comfortable with, say, giving a rating to a Senegalese restaurant after having only tried Senegalese cuisine for the first (and perhaps only) time.
