The boat features all-armchair seating, and all facing outward, so it’s kind of a cozy, relaxed setting in the first place, and with tasty little brunchy nibbles (pastries, fruit, salmon, etc.) and a warm cup of coffee or tea, plus a champagne toast if you so desire, it’s just a really pleasant experience all around. No, it’s not super-formal, but things don’t have to be formal to be elegant, especially not in Paris!
