London has a room with a view -- and what a view it is. On the eighth floor of the OXO Tower on the South Bank, this elegant restaurant serves Euro-Asian food with the latest trendy ingredients (oxtail with purple broccoli, for instance). The ceiling slats turn from white to blue, but who notices, with St. Paul's Cathedral and the London skyline across the water? The brasserie is cheaper than the restaurant, but both have great river views, especially in summer when there are tables on the terrace. Tube: Waterloo.
