There are a few after concert watering holes in Edmonds, all no more than six blocks from the venue. None Irish in nature.
Taki Tiki: Main St. between 5th and 6th Ave's. Just as the name implies
Rory's: Main St. close to the ferry.
Channel Marker: Sunset Ave, close to the ferry.
Lots of good restaurants pre-concert: Olive's Cafe and Chanterelle's are the best.
PS: This is a fixed seat theatre; what's the protocol for vertical movement?
