Craigie St. Bistrot gets 9.3 out of 10 from Citysearch and I think it deserves it. Despite the quality and price tag indicating a formal special-occasion restaurant, the place has a friendly style. The menu focuses on fresh, seasonal, and local ingredients in a decidedly French presentation and equally French wine list.
The equally well-rated Evoo, however, remains my favorite Boston-area restaurant.
