This was the restaurant that the No1DP and I went to celebrate our one-year anniversary. I first heard about this restaurant as a suggestion made by another Yelper and I told the No1DP to \"take me here on our anniversary\". Definitely a keeper.\n\nCONCEPT: This restaurant is one of five Milos restaurants from Costas Spiliadis. \"Estiatorio\" is a type of Greek restaurant that specializes in grilling but doesn't grill up just standard \"taverna\" fare. What the Milos family of restaurants are known for is their dedication to bringing in fresh fish from the source. Yup, they actually FLY THE FISH from the Mediterranean or from the East Coast. This is why most of the fish is sold at market prices. Upon request you can also shop at the fish counter to select the fish that would be served to your table.\n\nVENUE: Located in the third floor of the Cosmopolitan, the same floor as Jaleo, Blue Ribbon and Secret Pizza. Look for a door with \"Milos\" on top.\n\nThe restaurant layout combines the rustic terrace dining one would envision when dining in a Greek estiatorio or taverna with the opulence and style of 21st century Las Vegas. When you walk in there's no mistake that you walked into a fine dining establishment but the space looks and feels more like a fancy dining hall. You are going to know your fellow diners quite well - with our wedding party talking and even singing it felt as if the No1DP and I were treated to a performance at the dining room table. \n\nI'm not sure what was going on at the floor above but there was enough activity that caused the floor to shake at the beginning of our meal; the No1DP thought there was an earthquake going on at some point. \n\nSERVICE: Excellent, as it should be for fine dining. The waiter, bussers and sommeliers were dressed similarly. It looked to be quite busy for a Saturday late night as it took forever for the sommelier to serve our wine - it was not brought out until sometime AFTER our fish was served. We informed the waiter about this and he felt really bad about the situation. He promptly brought our wines and we were not charged for said glasses. The way he handled the situation was excellent; not once did he lose his cool.\n\nAPPETIZERS\nOysters ($4/oyster): There were a few types of oysters when I ordered, a sweeter/creamier type as well as a saltier/briner type. I picked 2 oysters of both varieties. A raspberry vinaigrette accompanied the sweeter oysters and a salty vinegar accompanied the brinier oysters. I found out that i prefer the sweeter oysters as I appreciated the texture of the oyster rather than the briny water soaking it. \n \nMaryland Crab Cake ($32): Hand-picked, fresh jumbo lump crab. The cake was slightly smaller than my palm but the cake consisted mostly of fresh crab and tasted rightly so. No1DP says that this is the 2nd best crab cake he's ever tasted with the best one actually being in Baltimore. I don't have any comparison so for me this was the best.\n\nMAIN COURSE: ~1lb Sea Bass. When ordering your fish you can have it prepared in several different styles. No1DP asked for our fish to be steamed. This portion was quite big and was lightly seasoned with herbs, lemon and capers. You can taste the freshness of the fish, No1DP says that it's like tasting fresh fish back in Japan. Sea bass is supposed to be a \"tougher\" fish but I could still easily cut the fish apart with a fork. Though the fish is filleted we were warned that there could still be bones in the center.\n\nOur white wines went well with our fish.\n\nSIDE: Grilled Vegetables ($31): Eggplant, Zucchini, Yellow Squash, Baby Fennel Cipollini Onion, \"The Real Greek Mint Yogurt\" & Haloumi cheese. This was the best grilled vegetable dish I have ever tasted. Looks like this dish was grilled and buttered. The veggies were very soft and kept their flavors. The Haloumi cheese was tough enough to taste like meat. It went VERY well with the yogurt. \n\nDESSERT: Chocolate Sin, \"the famous Milos Chocolate dessert from Athens\". This was a standard chocolate cake but it was still delicious.\n\nThanks to Liv K. for making this recommendation! I'll definitely spread the word that this is one of the good restaurants the Cosmopolitan has to offer. Supposedly according to many a Yelper they have an awesome lunch special...
