Gymboree Group has filed bankruptcy for the second time in two years — and it looks like this is really the end for the children’s clothing retailer. All Gymboree stores, including the one at Westfield Montgomery mall, are expected to close by May. Gymboree is trying to find a buyer for its higher-end Janie and Jack chain, which also has a location at Westfield Montgomery. We’ll keep you posted on the fate of that store.
