2nd Saturday offers a table selection, not a seat selection.  For each concert, you will have to select a table with open seats with enough room for you and your guests.  If table 2 for example has one person seated, then there may be only 3 seats left at that table. You will have to seach the tables for enough room for you and your guests.  If you have trouble, please send an e-mail to brady@2ndsaturdaycafe
Here is a seating chart for your reference.
