A nice $20 bill can get you that table seating when there are no ADR's to be had.
It was fall 2005. Me, wife, daughter, and wifes parents were all hungry. It was 5:00pm, and the weather was fine. We wanted to eat on the patio at alfreados. 90 minute wait.
Gave the guy taking names a handshake with a $20 in it. he clapped his hands, said some italian....and 2 tables were pushed together for us imediatly.
Don't underestimate the value of a $20 and a handshake when you want something above and beyond.
