Sometimes when dining in the signature restaurant of an upscale hotel, there\'s the misplaced belief that if the place is decorated in a suitably grandiose fashion and the menu is tweaked to feature the requisite number of luxury ingredients, then the restaurant will succeed. This, in fact, is far from true. An amuse bouche at the start of the meal, a few petit fours at the end and the chance to spend a huge amount of money on caviar (Dh1,100 for 50g of French Sturia d\'Aquitaine at this week\'s restaurant) does not a great meal make. At the St Regis hotel on Saadiyat Island, 55 & 5th, The Grill is housed in a stylish, classically decorated room with gleaming, oversized light fixtures dangling from the high ceilings, sumptuous leather seats, heavy white linen tablecloths and shiny black veneer floors. The menu, meanwhile, offers a selection of the aforementioned caviar and dishes featuring black truffles, oysters, turbot (the king of the sea) and Wagyu beef. The service was certainly well meaning when we visited, but the overall effect was awkward: a waitress hovered behind my friend as she sipped her water, it jarred slightly when our orders were repeated back to us loudly (I understand the logic of this when a large order has been placed, but when it\'s just two desserts, it seems odd) and when we asked for the bill, we were first presented with the wrong one and then the right one took a good 10 minutes to arrive. In short, it felt as if something was missing - a bit of direction or assurance - and this feeling was echoed in the food. My friend\'s starter was a prime example of this. Three scallops were served with \"potato risotto\" (creamy, textured mashed potatoes and leeks), a thin piece of crisp chicken skin and chicken jus (gravy). What sweet, mild scallops were doing among these robust, British Sunday lunch favours, I\'m not quite sure; the individual components of the dish might have tasted perfectly nice, but they certainly didn\'t work together. My layered Wagyu beef crudo wasn\'t a roaring success either. The wafer-thin slices of raw beef had been cut into neat squares and covered with a Parmesan and herb spread, which masked the flavour of the meat completely. This was a real shame, particularly given that when you order Wagyu beef, you really want to be able to taste it. The restaurant prides itself on its \"vintage beef from the ageing room\" and, it must be said, my friend\'s 28-day aged Wagyu striploin was well cooked, with a charred, salty crust and a tender, rosy pink centre. A bowl of bearnaise sauce (her chosen accompaniment) was fine but the chips were disappointing; although crisp on the outside, they were dense rather than fluffy in the centre, which caused us to wonder if they had been cooked from frozen, rather than hand cut and fried fresh. Once again, my main course just didn\'t feel like a well thought-out dish. For a start, it was small - more akin to a starter size dish than a main course - and as soon as I saw it, I wondered why our waiter hadn\'t flagged this and suggested that I order a side salad or portion of vegetables.
