Pike Kitchen, Rockville’s second all-Asian food hall, opened its doors this week at the Edmonston Crossing shopping center on Rockville Pike. Inside you’ll find nearly a dozen locally owned eateries serving poke bowls, ramen, scallion pancakes, fried seaweed rolls, popcorn chicken and other Asian delicacies — along with beer, bubble tea and homemade ice cream. The appetite for these Asian food halls seems to be growing: The Spot has been bustling since it opened last July near Rockville Town Square, and Pike & Rose is building one of its own called The Block.
