A loft is a very handy kind of space, with practically no restrictions attached. Typically, these spaces are free of furniture, so you can bring your own and set it out as you please. As a rule, lofts have high ceilings which measure at least 4 metres. Many of these venues are located in industrial zones, on the premises of former factories and warehouses. This should mean that you are free to play loud music and dance.
Guests at a buffet eat standing up, picking up as much food and drink for themselves as they like. It may be better to have a venue without too much furniture for this, so that people can move around freely as they mingle and eat their fill.
