The fiery "Hell's Kitchen" chef, who already has two restaurants -- The White Room and Frankie's Bar & Grill -- aboard P&O's latest ship Ventura, has now updated and upgraded two more eateries on Aurora and Oceana.
The Cafe Jardin galley and restaurant on Oceana was upgraded during a recent refit and served the new dishes last weekend on a two-night cruise whilst Aurora's Cafe Bordeaux opens its doors this weekend for passengers to sample the new menus.
Marco will serve up classic Mediterranean meals such as quail's eggs Hollandaise, Marco's confit de Canard (duck) and pannacotta with poached pears.
Sound tempting? Keep in mind that as with many alternative dining venues, lunch and dinner in Cafe Jardin and Cafe Bordeaux come at a price. These vary depending on the length of the cruise.
Prices for lunch are classed as "free," but meals such as fillet of beef or seafood carry an additional £2.50 supplement. Dinner charges range from £4.99 per person for cruises of eight days or more, to £7.75 per person for short cruises of two days.
