We recently had a birthday celebration dinner at this wonderfully authentic French bistrot in Danville. The setting is lovely as the restaurant is tucked away from the street and you enter by walking through a lovely patio where they offer outdoor dining. The place is run by French ex-pats and the chef is from France as well. Service was excellent and the food reminded us of what we've had in France.
I can't say this place is as fantastic as Bistro Jeanty, but I think it comes close. Regardless, it must now be one of the top places in Contra Costa (it opened this past summer). Certainly if you're over that way, you should check it out and a special trip may even be in order.
