Hard to say whether it's the mood lighting, the couches that encourage guests to settle in for another drink, or the young professional crowd that makes Le Colonial's French-Vietnamese lounge an excellent spot for flirtation. But whatever it is, it works. Drop in for a glass of wine and some spicy crab cakes and you're bound to catch someone exchanging spit behind a banana plant or bamboo room divider. If you're lucky, one of the people doing the swapping will be you.
