Most expensive sandwich

The most expensive sandwich commercially available is the "Quintessential Grilled Cheese" which sells for US $214 (£132.64) at Serendipity 3 in New York, New York, USA, as of 29 October 2014. The Quintessential Grilled Cheese is served on two pieces of French Pullman champagne bread which is made with Dom Perignon champagne and edible gold flakes, with white truffle butter and the very rare Caciocavallo Podolico cheese. The sandwich is served with South African Lobster Tomato Bisque as a dipping sauce.
