TasteCard and Gourmet Society Card
Regular diners will appreciate the BOGOF and 50% off deals the Taste London discount card (www.tastelondon.co.uk)will get you at restaurants like La Tasco, Prezzo and Strada. It costs £69.95 for a year's membership, but it's worth waiting around for a promotion (I grabbed mine for £35 a few months ago). If you eat out once a week, you're likely to have made your money back within the month. Gourmet Society (www.gourmetsociety.co.uk)do a similar card for restaurants like Loch Fyne.
