‘저희 마감 시간은 10시고, 3시부터 5시까지 브레이크 타임 있어요.’
‘마감 시간’ refers to Closing time. Orders can only be placed before closing time.
‘브레이크 타임(Break time)’ is a short break in the middle of business. Usually from 3:00 to 5:00, after the lunch business is over, I have a break before the customers gather in the evening. I take a break to prepare for business in the evening or because there are no customers.
Conversely, the time when the restaurant door is open is called ‘오픈 시간(opening time)’. It's good to go to a restaurant after checking the opening hours, closing times, and break times.
‘6시는 예약이 다 찼고요.’
‘차다(full)’ means that the set amount has been reached. So '예약이 차다' means that you cannot make a reservation. Similar expressions include ‘예약이 풀(full)이에요’, ‘예약이 마감되었어요.(reservations are closed.)’, and ‘자리가 다 찼어요.(the seats are full’.)
‘자리는 창가석이랑 일반석 중에 어디로 예약해 드릴까요?’
A window seat is a seat next to a window and is referred to as a ‘창가석’. A regular seat is a seat inside the restaurant that is not next to a window and is referred to as a '‘일반석’ . An outdoor seat is a seat outside the restaurant and is referred to as an ‘야외석’ . A space on the roof is referred to as a 'rooftop' and when you want to find out if there are any seats on the ‘루프탑’, say ‘루프탑에 자리 있나요? (Are there any seats on the rooftop?)’
