You know that restaurant which somehow becomes your go-to for a great weekend meal out? The restaurant where everything is good, even though you can't always remember exactly what you had? Petit Louis is that restaurant for us- mostly because of its ambience- which is not at all stuffy but proper in a properly French way.It is a true French bistro with great steak frites, and the best profiteroles I've ever had. Extra points go to the affordable and well edited wine list... Petit Louis is tucked in beautiful Roland Park, which makes it a great meeting place for city and county folks alike.
