The O2on2-All Day Dining Restaurant introduces new choices to its lavish international buffet, from live shrimp and oysters to sea crabs. The regular selection of hot and cold dishes, noodles and desserts is available.

Freshness, of course, is essential.

Every morning around 7:30am, Wolfgang K. Uebler, executive chef of The Longemont, goes to the receiving department, checking the quality of all seafood to ensure everything going to the kitchen is fresh.

All seafood is packed on ice and covered with damp towels, since it must be kept cold and moist. Around 16 types of seafood at The Longemont are imported from Norway, France, Australia, New Zealand, Thailand and Vietnam - all with different climates favoring different species.

All domestic ingredients, including shellfish and shrimp are delivered daily, while some food, such as salmon and tuna, is imported three times a week.

Different cooking methods develop different flavors in the same ingredients. The lobster at O2on2 is cooked two ways, braised in cream and poached with home-made broth.

Braising enhances the natural flavor of the lobster, which is sweet and mild, and develops a creamy nutty flavor. The poaching - using vegetables, cloves, white wine and a little butter - gives the lobster a firm texture and refreshing light favor.

The oyster from O2on2 is a must-try. Before serving, the chef opens the shell in front of the diners to demonstrate that the oyster is alive. Squeeze some lemon on the top, pick up the shell and suck in one bite. It's like kissing the sea.

The oyster flesh is cold and creamy and mixes with brine inside the shell - it slips into the mouth and down the throat and leaves a sweet aftertaste. We recommend pairing the oyster with the light and crispy Premiere Sauvignon Blanc AOC on the wine list.

One of Longemont's star dishes is pan-fried red snapper on spinach, deep-fried leeks and almond-butter sauce.

The fish skin tastes crispy while the meat is tender, creamy. The almond sauce, when served with the meat together, has rich flavor and smooth feel. Leeks after being fried become crispy and fragrant.

Seafood indulgence at The Longemont costs 228 yuan (US$34.54) per person, with a 15-percent surcharge.
