We sailed on the Glory last October and had a cabin across from one of the unspecified areas. It was a storage area for the room stewards. We heard absolutely no noise from there. I can't tell you anything about the sushi bar, the oriental window (it's not a restaraunt, just a walk up area you order from) was very rarely open. Our friends went to it several times and it was always closed. Now, the buffet area might have a section with oriental food, though I don't remember seeing it. If you like deli type sandwiches the deli on the Lido deck has very good sandwiches. The Lido deck has the grand buffet, the deli, the oriental, all inside, outside is the pizza (best pizza) the hot dog & hamburger grill. There is also a fish and chips area upstairs in the Red Sail. Plenty of food to choose from, you won't go hungry. The Glory is a great ship. Oh, you will enter the ship in the Lobby, deck three. There are deck plans of the ship on the counters, pick one up to help you find your way around, you will need it for day or two. Enjoy your cruise.
