Across the street from Haha Donkatsu is Pho 32, a Korean-owned place specializing in the Vietnamese soup called pho and shabu-shabu, where you cook meat, seafood and vegetables in hot broth on your table. It is around the corner from a Vietnamese-owned pho restaurant called Mo' Pho. Haha Donkatsu specializes in breaded pork cutlets, and I had mine diced and added to a bowl of Korean bibimbap -- steamed rice and julienned vegetables ($8.99 with several side dishes). The sauce you add is truly spicy.
Today, as I returned from ShopRite, I saw what looks like Hackensack's first Korean restaurant (the city already has a Shilla Korean bakery on Main Street, near the Sears parking lots). I didn't catch the name, but signs offer barbecue and shabu-shabu. This is a small place that has housed a number of unsuccessful restaurants, between The Record and Pep Boys.
