Finally got to Petit Robert last night. I really wanted to like this place, I crave authentic French bistro fare. I found the space a bit odd, with tables on the banquettes too close together (though there was a certain authenticity to that). Welcome was fine, service was efficient. I had the "heart attack special", French onion soup and steak frites with bearnaise. The soup was delicious, one of the best versions I've had, not too salty, delicious cheese, great clean taste to the broth. My DC had the salad with panko-crusted goat cheese. The salad was very overdressed, and the goat cheese, while tasty, had too much breading, and mostly tasted fried.
My steak frite was pretty good, the skirt steak perfectly cooked as ordered, and fairly tender. The bearnaise sauce was fantastic, you could tell it was freshly made, with a strong tarragon flavor. The fries were OK, too thin and much too salty. My DC's duck was very good, though not exceptional, he said.
For dessert, I had the gateau petit robert, a liqueur-infused chocalate cake, with rolls of white chocolate on top, and accompanied by a chocolate eiffel tower. The whole effect was great, but I found the cake dry and the liqueur flavor too strong.
Had 2 glasses of Chateau Bonnet, which was delicious.
Dinner for the two of us ran about $110 with tax and tip, not too bad. I'd try it again, but would order one of the sauced fish dishes next time, I think.
They said the South End version is opening next Tuesday, and will have valet parking, a big plus.
