La Petite Maison in Sandy Springs is a charming little French bistro to take your trust fund grantor or bridge partner for a leisurely lunch. It’s nice for days when you’ve got no place to be—white linens cover the tables inside and out, and the enclosed patio is lined with string lights and plants. During lunch, the place hums with gentle music and gossip about wayward grandchildren. Folks, mostly likely fresh from the salon, linger over hearty ratatouille and cups of french onion soup capped with a hardened glaze of cheese. The food here comes second to the friendly, relaxed atmosphere, so plan on reaching for the salt if you order the linguine with housemade pistou.
