This is the sort of place that counts the Twigglets that they serve with your drinks. Talk about doing the bare minimum for the customer. I ordered the lamb which was quite nice but it came with just half a tomato and one small re-heated roast potato! This cost 25 euros. For 25 euros I have eaten brilliant set menus. The Comptoir des arts is there for the staff to pose in and to exploit tourists. I would rate it one of the most cold-hearted and cynical places I have ever eaten in in France.
The only good thing to say about it is that the snail's pace service gives you plenty of time to enjoy the view from the terrace. Avoid unless everywhere else is closed and starvation beckons.
