Cajun dish was great, first trip to New York City was told that we just had to check out S'macs. We did, placed our order 26 in our group. But the restroom stench and general uncleanliness along with graffiti filth was enough knowing employees also use that restroom to never want to eat there again. If I had seen the restroom prior to ordering and paying I would have left.
S'macs, get it together. Should I return I will definitely check the cleanliness out of the bathroom before I sit down and eat and hope that the employees hands are is clean. Word of mouth is everything!
