Can cater for larger groups, but emphasis is on drinks not food. Not very authentic New Orleans chain.

Ole is both - a complete Spanish Chic dining experience and lively and informal neighbourhood bar and restaurant. The excellent food, service and background music will want you to return again and again.
Specialising in modern Spanish cuisine, the carefully prepared and artfully presented menu ranges from freshly prepared variety of tortillas, through a pork loin to a salad of chicory, apples & walnuts.
Located 1 minute from Fulham Broadway station, Ole offers one of London’s most pleasurable bar/restaurant experiences.

London SW1X 7RN 020 7290 7101 Modern French/Mediterranean 7 days £20-£30
Part of Sheraton Park Towers, but easy to miss, this is probably London's most underrated restaurant. Clean modern decor with uncrowded layout. Food and service are consistently good with the lunch time menu being fantastically good value for money; two courses cost about £19 and three about £24. Dinner is more expensive, but still worth the money. If you like fish, this is definitely the place to go although other dishes are great too.

The brainchild of Huseyin Ozer, OZER's cuisine highlights the freshest variations of fish, seafood, vegetables and fruit. The dishes are accompanied by the lightest of sauces and herbs, enhancing but never detracting from the flavour of the main ingredients. The speciality lamb dishes are amongst the most exquisite in Europe, as are the meze.
Ozer has an excellent value set lunch menu at £14.95 for 2 courses which is also available early evening.

Reportedly the best of Conran's restaurants in London. Smaller than most others, with just 30 covers and a mroe subdued atmosphere. The chef, Chris Galvin, was awarded a Michelin star for his food.
Lunch offers a good value menu du jour at £23.50(closed Sunday lunch), and a menu Gourmand is available at dinner for £50 (£80 with matching wine).
Review The OrreryOxo Tower Wharf
Bargehouse Street
South Bank SE1 9PH 020 7401 2255 Fusion Mon-Sat £30-£50
The rooftop Oxo Tower Restaurant, Bar and Brasserie has proved a dazzling success since it opened in September 1996. Both the formal restaurant and more relaxed Brasserie and Bar have stunning views across the Thames to Charing Cross and the City of London.
The menu features a series of 'classics with a twist', as well as a sprinkling of dishes combining Mediterranean/Pacific Rim and French/Asian ingredients. The impressive wine list includes 350 different varieties.
The interior was designed by award-winning architects Lifschutz Davidson. A unique louvred ceiling with blue neon lights creates a beautiful moonlit effect in the evenings. Leather-clad bars and slate tables add to the subtly luxurious feel. The ambience is further enhanced by original art and with the miniature Harvey Nichols Foodmarkets in the reception areas.
