I am working in North Beach, SF. That is the italian neighborhood. Little Italy! There are a lot of pretty good Restaurants here. A lot of Pasta & Pizza :-)
Some of them are pretty successful. And some not! At some locations every 6 month another Restaurant is opening. This nice spot here is empty again.
A couple months ago it was a france Restaurant. But now they are bankrupt.
No wonder! The rent for a nice Restaurant is ridiculous high here in North Beach. The rent for the nice Restaurant on the image is not less than $6500 per month. In average you pay $5 for a beer and between $10 and $30 for a good meal. If you do a simple math, you will realize that you have to sell a lot of drinks and a lot of food to pay the rent.
