It is a shame that Cluny falls into the category of good food ruined by terrible service.
I have dined at Cluny a few times in this year and have been bothered by the lack of check-ins and water refills. In my most recent visit, we had to start packing up in order to get someone's attention to bring a credit card machine over. (Sometimes I wish I could stand up and wave someone down like in Chinese restaurants...)
That being said, I do actually find the food pretty good. The tomahawk veal meatball is great and I have yet to find a restaurant that does souffle consistently well. Cluny probably still has the most reliable food in the Distillery District that isn't outrageously expensive.
I would return to Cluny, but I hope the service can be stepped up.
