Amazon has opened its second Manhattan store, this one on 34th Street at Herald Square. As with the chain’s Boston and Chicago locations, this store includes a cafe, featuring coffee by Stumptown and a selection of pastries and snacks. Amazon is apparently doing some merchandising experimentation as well, offering a variety of related and barely-related products in the bookstore. Some you would expect, such as Amazon Echo devices. Others are a bit curious, like the guitar-shaped ice cube trays, drink tumblers and Wonder Woman alarm clocks, made by Lego.
