The tiny, French sister of Antoine Alliaume's Curbside Cafe may not be as well known as it should be. But that's a good thing, when you think about it, because what better way to impress someone special than taking her to a place of which she's never heard? Reasonably priced, classic French dishes -- the chicken stuffed with crab velouté and the rack of lamb with rosemary demi-glace being two of our favorites -- are served with seasonal vegetables so artfully arranged it will seem almost a tragedy to disturb them. Of course, you will disturb them, and, after the first bite of your entree, you'll discover the real reason Too stands out: les sauces.
