The invention relates to a modular galley for an aircraft or train. The modular galley comprises a wall (1) provided with a multiplicity of guides (2) running in the vertical direction with undercuts as well as a multiplicity of essentially block-shaped modules (6-12) with runners (14) on the rear that can be accommodated in the undercut slots (2), the cross-sectional shape of which, viewed in the horizontal plane, corresponds to the cross-sectional shape of the undercut slots (2), viewed in the horizontal plane. The modular galley furthermore comprises lifting means (4) for raising or lowering a said module (6-12), the runners (14) of which have been accommodated in a said undercut slot (2), over the wall. It is preferable if the slots (2) are widened in places (17) such that a runner (14) can be inserted here in the horizontal direction so as then to hook into the undercut slot (2) after being moved vertically.
