They do not take reservations.
No, but if you go early, especially on weekdays there is no wait.
No, and there might be a significant wait. Plan on showing up at least a half hour before you'd like to eat.
The person on the phone said no, but call ahead and see what the wait time is. One person can come in and put their name in for the group and get a table when it comes available and hold it for the group.
