I checked these guys at last night at the Quartier des Spectacles. It was tough to pick a food truck, as they were all set up at exactly the same time. However, all I could think about was grilled cheese with bacon. Enough said, right?
I was pleasantly surprised at the size of the grilled cheese - I was worried it would be ginormous, but it was the perfect size for one person (i.e. regular bread was used). The cheese had a strong flavor - a bit stronger than I normally like, but the caramelized onions and bacon balanced everything out perfectly. Despite the fact that it's a load of carbs, the sandwich was surprisingly light. My personal preference would be for thinner, crispier bacon though. I think they use peameal, which is thicker. I found it a little chewy for my taste.
Otherwise, c'est bon!
