1. President Reagan once received a shamrock from TB's... in the Oval Office
It happened in 1983 on St. Patrick's Day, and he's not the only Cali politician who has a link to the bar: Mayor Garcetti bartended there for St. Patrick's Day in 2014.
2. One of the booths essentially belonged to Cary Grant
His shamrock is still there, too.
3. Bing Crosby, John Wayne, and... Julia Roberts have shamrocks
Kiefer Sutherland also has one, but that makes absolute sense.
4. There's no set way to get a shamrock
There used to be a punch card... and then there wasn't. There used to be a set number of drinks... and now there isn't. Basically, they have to really, really, really like you. Like, a lot. There was a period of my life when I was there four times a week, and I don't have a shamrock. So, like, five times a week at least?
