At night, about the only time I can countenance making the perilous, 90-minute journey across town, Canary Wharf shimmers like a magic realm, the top of the tower wreathed in clouds that enhance the mystical air. Ubon is tucked behind the swish new Four Seasons Hotel, surrounded by clipped lawns in a building, part lighthouse, part metal-clad Mayan-style structure, that reminds me of the Altar de la Patria in Santo Domingo.
