Might have been a problem docked in NYC during the summer months. NYC in the early part of the century was not the most sanitary place to be. Lots of flys. Tons of horse droppings.
It seems the meals and drinks offered at The Café Parisien did cost extra above the ticket fare, although when the bill needed to be settled remains unclear. The page below states that the same staff as the A la Carte Restaurant also cooked and served the first class passengers in The Café Parisien, overseen by Chef Luigi Gatti.Here's a question I've pondered for some time but not found a satisfactory answer to. The Cafe Parisian was operated by the A La Carte staff. However, my understand is that the A La Carte operated as a standard restaurant, with bills due at meal's end. Was it the same in the cafe? If one sat down for tea, light fare or even a drink would you have to settle your bill or was it charged to the cabin for later settlement?
Another question: were staff exclusive to the restaurant and the cafe, or were they swapped out during various shifts? Meaning one evening your waiter from the restaurant might be the same who serves you the next morning in the cafe.
A stab in the dark here, but I'm also going to assume that what you could get in the Cafe Parisian was different from what you could get in the Verandah Cafe. Is there a surviving list of options?
