Four couples are left in the running in as Raymond Blanc narrows down his search for his business partners. Each week Raymond selects the poorest performers and sets them a tough elimination challenge. Whichever couple fares the worst has their restaurant closed and their dreams shattered. This week Raymond has asked the couples to focus on the customer. His challenge is simple: it's dating night. Fill your restaurant with singles, give them the night of their lives and help them to find romance. But the couples don't find it so easy to spread 'the love'. Finding customers who want to go dating proves difficult - there's a mad dash along the Thames to find suitable singles, and a very high drop-out rate. Confusion in the kitchen over a romantic seafood platter for two leaves several guests without any food at all, and being the 'host with the most' leaves one contributor unable to run his restaurant efficiently. Tonight one more couple will leave the series and by the end just one couple will be left.
