Others have written about the superb ambience of the Belouga, I shall concentrate on the real issue - what we had to eat and the service. This was a big occasion, my wife's birthday.We enquired beforehand if I could bring my own wines as I felt, on our last visit, that the choices were either stratospherically priced or simply over-priced and mundane. The restaurant has a policy for 'droit de bouchon' of 20€/bottle. So I dived into our cave and took along some Pouilly-Fuissé, a Vosne-Romanée and a p.g.c St Emilion (to allow for a wider choice). Certainly not all restaurants have a corkage arrangement, which can vary from 10€ to 20€. This allowed us to have really good wines for a birthday without wincing so much.The carte offered among others a Seasonal Menu at the whim of the chef, entrée + main-course + dessert, for 70€. The chef provides food on a seasonal theme for the first two courses with two or three amuse-bouches in between - then you choose your dessert from the carte (about 6 delightful, naughty, available). In our case, the theme was lobster and this translated into an entrée of pieces of claw on a bed of firm potato puree and framed in 'bangles' of crispy potato, ultra-thin and crispy, perhaps 20 thin rings - a delight for the eye and the crisp rings went very well with the texture and taste of the base. The main course was the body of the lobster - about half the body meat still in the tail half of the shell and a red, cheese-coated, sauce in the other half. It looked delightful, but one wondered where the rest of the body meat had gone. The sauce was a little on the rich side, but since we were washing down with a 2005 Pouilly-Fuissé, we were not complaining! The desserts were superb, but not for anyone trying to hold their weight down. Sugared brulée strawberries, a superb Kouign-Amann (Breton speciality raised to Michelin heights)...The service was spot on, we didn't have to wait much between courses and house-made bread rolls and specialty salted butter kept coming.So why am I holding back on the stars? And why my subject heading?Amazingly, and inexplicably, when the main course of 4 servings of lobster arrived, one of them was undressed with no red cheese sauce. It was offered for any one of us to have, whilst the others had the 3 dressed servings. This was unacceptable and I asked for a fourth standard serving. Since the course was served hot, I asked the others to start without me and then sat for some 10 mins waiting for mine. This was stupidly, and unnecessarily, annoying and I was amazed that it could have happened in this way. Further, I felt that the size of the entree and main were rather small - the entree made from the claw was just a couple of square inches of claw, so someone else had the rest. And the main course had half the body meat of only half a lobster, so 3/4 of each lobster also went to some other diner's plate. A thematic meal based on lobster, at these prices, should at least have given half a lobster each, if not perhaps a whole lobster, as would happen at other good Breton restaurants.Hence my degraded ratings.A totally unnecessary stain on their reputation.
