No doubt it helped that, when I went there on a Tuesday lunchtime, only half the tables were filled, but I gather it's packed in the evenings. It attracts an older, moneyed crowd drawn from the residential streets off Gloucester Road. (One regular described the typical L'Etranger customer as a French sugar trader with a holiday home in Mauritius.) Rather predictably, the man at the table next to mine had his mobile permanently glued to his ear.
