Restaurant reservations: Setting preferences for seating, such as indoor, outdoor, or specific views.

💬 [したい] attaches to the verb stem to say you want to do something: [予約したい] = want to reserve, [座りたい] = want to sit. In polite speech it's often followed by [です], as in [したいです].

💬 Japanese often says [verb + たいです] for "I'd like to ...": [予約したいです], [変更したいです]. It's a softer, more natural customer phrase than a blunt command.

💬 [の] between nouns lets the first one describe the second. Here [いつのご予約] is literally "which-time reservation," meaning the reservation for what date or time.

💬 The [ご] in [ご予約] makes the noun more polite. You'll hear this a lot in service situations: [予約] becomes [ご予約], [希望] can become [ご希望].

🇯🇵 Staff often use extra-polite forms like [ご予約] when speaking to customers. You can use plain [予約] yourself and still sound perfectly fine.

💬 [いつ] means "when," but with [の] it can narrow down a noun: [いつのご予約] = reservation for when. The whole pattern is useful with other nouns too, like [いつの電車] "which train / the train for when."
