What role does the additional galley serve on certain ERJ 175 aircraft?

The additional galley on certain ERJ 175 aircraft primarily serves as a food service area. This feature enhances the aircraft's ability to support meal preparation and service during flights, catering to passengers' needs more efficiently. By including an additional galley, airlines can provide a wider variety of food options, improve service speed, and accommodate higher passenger loads. This setup is particularly beneficial on longer flights where meal service is expected to be more extensive.

While options like emergency storage, passenger assembly point, and equipment storage may play roles in some other contexts, the primary functionality of the additional galley is focused on facilitating the catering services aboard the aircraft.
