Most restaurants have a reception counter except some small
ones in outlying islands or small residential areas.
Restaurants with reception: If there is table
available the usher will take you there. If not, you will be given a piece
of paper with a number on. They will shout/announce with a microphone
or show the current ticket no. on an electronic board when it's your ticket
Restaurants without reception: Get a waiter to help
you to find a table or you may sit on any empty table you can find. In
very few restaurants, you may be arranged to share a table with someone else
which is a bit weird by western standard.
