Paris
Pros
-- the cafe culture
-- beautiful city
-- very walkable and with good public transportation
-- tons of cultural stuff from the opera and the big museums to very small, say 40 seat, performance venues and store-front galleries
-- fresh bread everywhere (even though Parisians say you can't get a good baguette anymore)
-- it was easy to become a regular at the cafes and restaurants in our neighborhood
-- you can smoke a cigar at any cafe/bar/bistro terrace
-- train travel from Paris to London, Amsterdam, Brussels, Marseille and many other cities is easy and fast if not always cheap.
Cons
-- the winter months are solid grey and overcast and drizzly
-- no decent Mexican food
-- they all speak French here
