The Tel-Aviv "New" Central Bus Station and its area. The station itself is an enormous, if grotesque, concrete monstrosity, which used to be the largest bus station in the world until recently. Construction began in the 1960's and went apace until 1993, in the meantime its promise of an economic paradise with a massive influx of shoppers for all the concessions faded, many people lost the money they put into purchasing shops there. The result is a huge, partially abandoned structure - almost an arcology in size - in bad maintenance. The two lower floors - which are underground - are almost completely abandoned. Instead, all sorts of shady businesses filled the "ecological" vacuum - pawn shops, cheap phone shops, some street food places, alongside several legitimate businesses. There is also a problem of petty crime and drug use. Meanwhile, this is still a very major transit hub, as most bus lines going in or out of Tel-Aviv stop or start there.
The better part of the station is actually the area where Philipino immigrants opened several shops, which are well taken care of and have very good imported Asian food and ingredients for decent prices - which you can hardly find elsewhere in Israel except for very upscale and expensive places.
Outside the station is a run-down international area. This area mostly holds immigrants from Asia and asylum seekers from East Africa, as well as their businesses. This is where "guest workers", immigrants, and asylum seekers go to shop or to relax after their long work hours. They have shops, restaurants (some of them very affordable and good), and bars/hookah places. Many asylum seekers also live in the area, where rent is less expensive than in the rest of Tel-Aviv. City hall invests very little in the infrastructure and most buildings are old.
There is, of course, a major crime problem in the area, though most of it is run by Israelis who were involved in criminal activities even before the immigrants and asylum seekers came. This has several brothels ("massage parlors" and "pay-per-hour hotels"), including a very conspicuous one which is a block away from the local police station, and a good number of drug users (and pushers).
As usual for a transit hub in Israel, this area is full of soldiers going to and from their bases. They are a major source of business. A good number of them, of course, carry assault rifles - as the IDF issues guns to soldiers on leave in many cases. While there is a nearby police station, you rarely see civilian "blue" cops in the station itself. Instead, due to the recent wave of terrorism, the government has posted Border Guards at some of the entrances to the station to defend against attacks. These are conscripts belonging both to the IDF and the police at the same time, with law enforcement powers. The ones posted at the station are usually young women around the age of 18, fresh out of boot camp and basic Border Guard training, armed with assault rifles. They rarely deal with crime but rather "guard against terrorist attacks" - in practice they spend their long shifts playing with their cellphones, or chatting with the station's security guards posted nearby. From time to time they inspect people who look "suspicious" to them for their papers and usually look as if they feel very "important" when they do so.
In short, this is how I'd imagine a Starport-D or even Starport-C startown in the Hard Times or The New Era.
