A reservation is a must at any restaurant when you are a large group. You should call as soon as you plan the event. Let them know how many and can they accommodate your group at one table or will they have to break it up. The next thing is be sure everyone arrives on time. There are many other things like letting them know what the occasion is like birthday, or graduation or anniversary.
Would be a good idea
Yes, to be sure you and your guests can be seated comfortably and promptly.
