Ask not what you can do for your neighborhood Chinese restaurant but what it can do for you: deliver. If you live out of range, however, it behooves the salmon lover to hoof it on over to East Emerald and pick up an order of Emerald salmon with black bean sauce to go. By the time you get home, the bean sauce has soaked into the fish, rendering it a bit moister than you might actually get in the restaurant. Chef Kevin Ong also excels in undercooking vegetables just slightly, so food packed in cartons is perfectly done, steamed to ideal consistency. The restaurant will even pack up a Peking duck, which in our opinion goes above and beyond standard takeout fare. But then, East Emerald isn't named after a precious stone for nothing.
