Ordering a coffee Part 2 (Advanced): Options such as type of milk, depending on dietary preferences or allergies.

💬 [一つ] is the general counter for one item, often used when ordering: [一つ], [二つ], [三つ]. For drinks, staff may also use cup-specific wording, but [一つ] is very common and safe.

💬 [お願いします] is a very flexible polite way to mean "please" in service situations. You can attach it to lots of choices: [ホットでお願いします], [少しだけお願いします], [オーツミルクでお願いします].

💬 When ordering, [Xを一つお願いします] is a very reusable pattern: item + [を] + quantity + [お願いします]. You can swap in other items too, like [紅茶を一つお願いします] or [サンドイッチを一つお願いします].

💬 In lists, [と] means a straightforward "and": [豆乳とオーツミルク]. For choices, Japanese often uses [AとB、どちら] — literally "A and B, which one?" — where English would say "A or B?".

💬 [どちら] is the polite "which one?" for a choice between two things. For more than two options, you'll often see [どれ] instead.
