There is no reservations required.
Monday is not really an issue trying to get it seat you don't really have to wait that long on Mondays is not a holiday it's a regular day so you should be okay
No, you do not have to make a reservation, but it is better to make a reservation since there will be a lot of people, but don't worry, if you don't make one the line moves very quickly!!!
Maybe you have to wait @ least 30 minutes
