There are lots of places you can go if you get there before Sirens. Bars and stuff, mostly, the night bus, and there's a one big shelter in the slum I think? Plus the free newcomer apartments are sealed up. Darkness-proofed, I mean.

If you're stuck outside and it's already dark, your best bet is the underground mall. There's three entrances in different parts of the city.
