1. To go to some place mainly for entertainment or sightseeing.
note: this phrase always has a meaning of a distance, so it can't be used for a type of a place, unless it's a specific place (Can't say "Let's throw our bones to the cinema", but can say "Let's throw our bones to Jam Hall")
2. Take a seat, especially when there is a choice what table/lobby sofa/seats in the airport/place for a picnic etc to occupy.
