I'd say urban is towny so not the countryside picnic side of romantic. What does the romantic towny do? Go out to restaurants, buy flowers from a flowershop, buy jewellery. The rural romantic would probably go out for a walk, have a picnic near the lake, pick a bunch of wild flowers .... saying this; this might well be what an urban romantic would do to be romantic!!!!!! Maybe associating the two where you see somebody actually buying flowers in a flowershop but dreaming of picking some in a field... Just a thought!
