Every Saturday, the back of this pan-Asian Gulf Gate specialty store transforms into a small Korean café. One staffer carefully prepares Korean-style sushi, while another slides a couple of small sauté pans over a pair of burners. The menu begins at $3.99 and includes fishcakes stir-fried with vegetables and hot chilies, fried dumplings, noodles tossed with root vegetables and pork and the bibimbap, a stunning mix of rice, veggies, roasted seaweed, pepper paste and a fried egg whose gooey yolk is whipped up until it coats everything in the bowl. If only they served this stuff every day of the week.
