I work three evenings a week at IKEA. I do 8.30pm until 12.30pm (the store's open until 12)and get home about 1am. Tbh I am tired most of the time (I live for school holidays when I don't have to get up in the morning!) but the advantages outweigh the disadvantages.
plus - no childcare, under the tax/NI threshold so all my earning are mine iyswim, get to be at home with DD, no worries about holidays, appointments, DCs being sick etc, regular money, possiblities for o/t, holiday pay etc
minus - money's good for the type of work it is, but not as good as a salaried job, so so tired, get very jealous of my nights at home so don't go out and also tend to stay up too late even when I am at home, social life can be complicated (but's that's mainly because I do fridays)
I've also done evening pub work - great socially, but money's dire and (depending on the pub/area) it can be a bit rough.
Done late night supermarket work as well, but it can be very depressing (very mind numbing) and the money, once again, isn't great (ASDA are apparently the best payers, and have 24 hr opening, but work you very hard)
