THE show-stopping lunch is back with a bang, if this short-but-sweet receipt from the restaurant at The Capital hotel in Knightsbridge is anything to go by.<br /><br />Our pair of well-heeled diners chose the &pound;33 three-course lunch menu &ndash; including such gems as a tiger prawn and coconut risotto, seared scallops with calf feet and braised cabbage, and roasted rump of lamb with olive oil mashed potato, followed by champagne and apple baba and tiramisu. <br /><br />Someone was evidently out to impress, however, since the wine they chose was a coveted 1995 Ch&acirc;teau P&eacute;trus, stumping up the bill by a tidy &pound;1,350.<br /><br />Coffees, cheese and one tumbler of Springbank 25-year-old single malt whisky rounded off the &pound;1,732.44 lunch.
