You finished this day
Getting a table
The first Korean you need in a restaurant comes at the door. Staff greet you and ask how many you are, using a word for 'person' that you never use yourself. Today covers that exchange, what to say when there is a waiting list, and how to ask where to sit. By the end you can get from the pavement to a chair.
At the door
Two lines you hear and two you say back:
Staff ask with 분 and you answer with 명, and both count people. 분 is the honorific one, so a server uses it for customers and you never use it for your own group: Korean honorifics are never applied to yourself. The -이세요 is the honorific form of 이에요, making the question roughly 'how many honoured persons would you be?'. 두 명이요 is a different shortcut: when a question only needs a noun in reply, you give the noun and add 요, or 이요 after a consonant. So it is 두 명이요 but 혼자요.
A busy evening
No free table, so there is a wait:
기다려야 돼요? has two pieces. -아야/-어야 means 'only if', the piece behind daily day 32's -아야 해요, and 돼요 means 'it works, it's all right', so the question is literally 'does it only work if we wait?'. After -아야, 돼요 and 해요 do the same job, and 돼요 is more common in speech. The waiting list is often a tablet by the door: you tap in your phone number and group size, and a text arrives when your table is ready, so you can wander off rather than queue.
Where to sit
Once you are in, the question is which table:
여기 앉아도 돼요? and the dialogue's 기다려야 돼요? are one syllable apart. -아도 means 'even if', so 앉아도 돼요? is 'even if I sit here, is it all right?', which is how Korean asks permission; day 38 of the daily course uses it for trying on clothes. -아야 means 'only if', and the same 돼요 after it makes an obligation. So 도 asks 'may I?' and 야 asks 'must I?'.
