Have to disagree too! I have eaten dozens of TCX Mr Martins meals and compared to the meals served on MON TOM VS and BA in steerage class, they are really good. The mains are tasty and the little box of goodies, particularly the Banana Muffin in the Breakfast is great. Even the veg is usually reasonable. The veggie options, Cheese Omelette and Gnocchi were the last ones I had, are pretty good too. The only complaint I have is the tea, which is diabolical!
If the Diabetic option was not up to scratch, I hope you filled in the comments card so they can do something about it.
