Was saddened to hear that Happy Joy, the great, cheap Chino-Malaysian place on Essex/Canal is to close, due to, what else, rising rents. Their last day will be Monday. Have been a lunch regular for years and do not know where I will find my fix of spicy curry chicken, the best beef chow fun around, eggplant in funky, sweet sauce, spicy Malaysian string beans or curry chicken noodle soup, a perfect sinus-clearing dish on a cold day. The gentrification below Delancey continues (Two Boots is about to open on Grand/Suffolk). Grab it while you can.
