As everyone has said it depends on who you are going to see. If it is someone who you think will sell out, then get there about 7/7:30 PM to stand in line and pay at the door (example being, if set time is 9/9:30 PM). They open at 11 am (?), so if you wanna go there and hang out until the show starts, someone will come around and take your money between 7 and 7:30 PM. If you go to the restaurant, you won't get a ticket, so don't make a reservation there expecting to get into the show (you still need to purchase a ticket, or wait in line at the bar). I think I might lobby the owner to start a selling tickets in advance. Since Iota is a smaller venue, tickets would disappear immediately, which is probably why they don't have that method right now.
