London's best Vietnamese-inspired eatery is spread over a series of dining rooms, alcoves, and bars in a town house with tattered French colonial decor. A favorite of young London, the restaurant is so popular that you may have to wait for 30 minutes to an hour for a table. The smell of lime and lemon grass lures you to the table -- this combination is married perfectly in the chicken in lemon grass dish. Equally worthy is the caramelized ginger chicken. Also try such delights as tempura of soft-shell crab, or crispy beef with papaya and crabmeat flavored with a lime dressing. Rock lobster and spring chicken hot pot is an eternal favorite, as are the flavorful prawns with green herbs and coconut. Our favorite starter is spicy raw beef with aromatic basil, lime, and chile, or fried marinated squid. A winner for dessert is the dish of sweet banana rolls with chocolate sauce.
