The sunset view from LES SAVEURS DE THAU The Étang de Thau is the largest of the string of lagoons or salt water lakes that run along the French Mediterranean coast from the outlet of the Rhone down to the Spanish border. These lagoons form an excellent environment for all sorts of fauna, from flamingos and herons beloved of photography buffs to mussels, oysters, and all sorts of fish for that fine, Mediterranean cuisine. So, when you attend a late afternoon concert in a village on the Étang de Thau, why not have dinner at one of the fine seafood restaurants that generally line the waterfront? I've written about restaurants in Gruissan, in Bouzigues, and in Sète . Now, thanks to Bach and a whirling Dervish, Mèze . (Yes, a Dervish performedd with Sufi chanters in a Protestant church in a small town on the French Mediterranean coast, right after a French group of singers and instrumentalists offered a Bach motet.. I'll be writing about that singular experience anon.) Int
