Cost of living in BA

Okay, so I've been here for about 2 days and I've have formed some ideas about the cost of living. Of course I'll need to be here a lot longer before I can really comment with any authority but my initial thoughts are that it's not as cheap as I originally thought it might be. Some things, like rent and travel, are dirt cheap but food and going out isn't. Then I spotted this item today about the global cost of living for expats and it seems BA is still relatively affordable. BA comes in at 138th. Moscow is the most expensive apparently. London comes in third.

We got the Subte (Subway) yesterday for the first time. Now that is cheap. 90 centavos. That's 17p. Compared to near 4 pounds in London! And such stunning stations.
