Walk to Union Square

I started walking and saw that the gas price is now above $5/gallon. That��s still about half the price compared to the price in Finland, but here the price has gone up 100% in the time it has gone up 50% in Finland.
Union Square was filled with art...
... and music.
Very touristic...
... but also quite pretty.
And the reason for the walk? To meet with Gregory and Greta, who took me for lunch to Grand Cafe, a place pretty fancy, which I didn��t expect. Fortunately, in SF, you can be dressed the way you feel like. And Greta felt like having some fancy stuff.
Oh, and related to gas. I saw this the day after.
