Is the third time a charm? Glover Park’s Kitchen (2404 Wisconsin Ave., NW; 202-333-3877) recently hired Alex McCoy, the restaurant’s third chef since its January opening. McCoy, a contender on Marco Pierre White’s NBC reality show, The Chopping Block, and former chef at Rugby Cafe in Georgetown, worked his first seven days as executive chef last week. Although several dishes, including lobster macand-cheese and chicken-and-waffles, have recently disappeared from the menu, co-owner Francis “Fritz” Brogan says the concept of the Southern-inspired restaurant will remain the same. We stopped by on Monday’s 25-cent-wings night to ask diners what they think of the new neighborhood hangout.
