Yourj: I don't think any menus survived from those two restaurants. The menus we have from Titanic are ones that passengers just happened to have in handbags, pockets, etc. when the ship sank. I also do not know of an a la Carte Restaurant menu surviving. So, sorry, there just isn't much information.
As only light refreshments were available in these locations there probably was no need for a menu. I imagine that if you entered and sat down a steward would approach and ask if you wanted tea or coffee, then perhaps a trolley would be wheeled to your table with a variety of cakes, pastries and other temptations available for selection.
Bob: It's my impression that these two restaurants functioned mainly for tea, is that correct? That would indeed entail trolleys of cakes and pastries, plus sandwiches like cucumber, chicken and shrimp (Feh! Anyone who wants my portion of shrimp is welcome to it).
Restaurants? They would surely never have been considered that. They were lounging areas where stewards could provide beverages and the lightest of (probably cold) fare. There was no facility for food preparation other than a very small pantry shared with the Smoke Room.
In a article I read that spanish 2nd class passengers the night of sinking they were into the Veranda Cafe, but I thoung this room only was exclusive to 1st Class Passengers. ¿Someone knows something about it?
In the spanish magazine "Sapiens" I read the 2nd class passengers E. Pallàs, told his nephew He and his travel compatriots were in the Verandah Cafe the night of sinking. For this tale, I have a doubts.
Even if it were possible, it wouldn't have happened. It was basically segregation. Even assuming the very small odds that a 2nd class passenger knew a 1st class passenger, and were both onboard together, separation of classes was part of the perks of a 1st class ticket.
