$2 Martinis at One Market Mad cheap drinks in Embarcadero

Did you know that the $2 bill, which was discontinued from 1966-1976, is currently the least produced US bank note, accounting for just under 1% of all new bills produced? Did you also know that if you have one of those (or, um, two $1 bills), and you order a main course at One Market, you can exchange it for a martini?? And that if you have another one of those (or, um, two more $1 bills), you can exchange those for a second martini???
