The first law of thermodynamics states that energy cannot be created or destroyed, but that it can change forms and locations. While we never understood it in high school, we think we get it now after eating at ZiZi. What Williamsburg lost when Zizi Limona (a utility spot that worked for everything from group brunch to dinner with parents) closed in September, Chelsea gained when ZiZi opened there a month later. The menu at this casual Middle-Eastern spot is almost identical, including a fantastic shawarma plate with juicy chicken and lamb over creamy hummus, and the space even looks similar, with lots of exposed brick, a small bar lined with wine bottles, and a couple of tables on the sidewalk outside.
