Given a travel related situation, and given a specific question about the situation, summarize the question into a title

[EX Q]: I will be arriving in Barcelona on the 13th of September and I will be staying together with my girlfriend for 6 nights. 

Although I have a job, as students the budget is, let's say, a little limited. The hotel and the flight were already pretty expensive, so we would like to know if there are some places where we could eat a good lunch at an affordable price (10 euros, let's say).

First we will stay in El Guinardo neighborhood, and afterwards in La Vall D'Hebron. Nevertheless, the recommended places to eat can also be in nearby neighborhoods of the previously-mentioned ones or somewhere as "downtown" as possible.

If you think I can easily find affordable places to eat by just exploring the city, that also works for me.

I hope I don't sound cheap.

[EX Q]: I'd like to go visit Istanbul in one of the next weeks; I'm not scared by it (I mean, things can happen anywhere), just concerned about possible consequences of taking photos.

I've heard a few third-hand reports about police -- before the coup -- being a bit harsh on photographers. Is it still the same, or even worse than that? Perhaps it has never been like that and those reports has just being exaggerated? I can evaluate how much risk I am prepared to take if I can get access to current information about the police.

I'd obviously avoid sensitive targets (policemen, military personnel and buildings). But I like to take photos of common places, too, so while I'll probably take photos of famous buildings I could take shots of common houses, telephone boots, generic skyscraper...everything that can make a good shot. But then, I've heard (from a friend of a friend of a friend...) that you can get in trouble with police if they think you are shooting things that they think are not interesting and thus you are not supposed to take photos of.

[EX A]: Can photographs be taken in Istanbul as of August/September 2016?

[EX Q]: I know this question was asked many times, and I read most of the answers, only my quest centers on the time that has passed since my overstay. 

Briefly, my story is I visited the US as a tourist from Argentina in 1993, and being there I wanted to try the experience to live there for a while, rented an appartment, could get a basic job as a driver doing deliveries, and ended up living for about one and a half years. After that, and realizing living as an illegal was a deadend with no promisory future, I just picked my things, bought a plane ticket and departed in 1994 never to return. 

Long story short, after almost 25 years, now I´m a professional, have a good situation and would just like to make a short vacation there. 

Here´s my main doubt; I´m not sure if it´s convenient or relevant to mention my overstay when applying for a visa, considering after such a long time they may not have record of that; or do Customs keep records for that long, and could backfire me here at the Consulate, or upon arrival at the airport? 

I add additional information 
To make things more interesting, I also have an italian passport. Since I am of italian descent I own the double citizenship. This passport grants me VWP, but that doesn´t guarantee automatic entrance, that´s why I chose to go with the argentinian one which needs a visa. I assume that having a visa makes entrance more likely since you underwent a previous official scrutiny; or does it not? Besides using a different passport could seem an obvious way to dodge that scrutiny and make it even harder.
