Concierge.com's insider take:

The always-packed Opal is known for its eclectic world-influenced cuisine and extensive wine list, with 300 vintages and 30 wines served by the glass. The bar does specialty martinis, such as the Perfect 10 (half Absolut, half Tanqueray Ten) and a mandarin-ginger cosmopolitan, and stocks more than 35 varieties of vodka. For starters, order the shredded phyllo-wrapped tiger prawns flash-fried and served with a coconut-curry dipping sauce. Signature entrées include the warm seafood salad (a mix of prawns, scallops, ahi tuna, and salmon served on baby spinach and salad greens) and the herb-grilled filet mignon served with whipped truffle-buttered Yukon potatoes and a wild-mushroom cream sauce laced with port and marsala.

Open Mondays through Thursdays 11:30 am to 2:30 pm and 5 to 10 pm, Fridays and Saturdays 11:30 am to 2:30 pm and 5 to 11 pm, and Sundays 5 to 10 pm.
