Translation of cadet in German

We decided according to whom we liked most and booked a trip for the next day. We looked for a place for lunch and found a restuarant called Pho 24, where they would serve soups for 24 hours.
So was the food. We ate French fries and a steak. We found that bizarre. After dinner we bought some books about the area and about South East Asia in general. They we second hand books.
We blamed the sandwich which we had eaten a day earlier for lunch in Bolivia for the stomach ache of my wife. She became very weak and she had to stay in the hotel for two entire days.
