Comedy and crabcakes

​The new comedy club, The Improv, in the Northland’s Zona Rosa shopping-and-entertainment complex opened this week. The attractive nightclub serves plenty of cocktails, of course, but it also serves food. Louisiana-style food, no less: gumbo, jambalaya, pulled pork, fried shrimp and praline cheesecake. The menu is an abbreviated version of the big, brassy restaurant and music venue right next door: Cleveland-based Fat Fish Blue, which opened two months ago.
