What locals say

Synthesized from upvoted comments on each city's subreddit.
Greater Tehran

Greater Tehran feels like a huge, layered metropolis where routines are shaped by traffic, bureaucracy, and the pressure of rising costs, but also by a strong sense of neighborhood life and adaptability. Daily life can be exhausting: commutes are long, sidewalks and transit are uneven, and many people build their schedules around avoiding congestion and dealing with practical hassles. At the same time, the city offers dense access to jobs, universities, services, and a food culture that runs from street snacks to serious restaurant scenes. People who live here often describe it less as a polished capital than as a place you learn to navigate through endurance, networks, and small daily workarounds.

Shanghai

Shanghai feels highly urban and convenient, but not always warm or easy for outsiders. Residents and visitors describe a city with cheap transit, strong food options, and impressive skyline districts, alongside real friction from language barriers, scammy dating scenes, smoky taxis, and a shrinking expat ecosystem. Day to day it can feel surprisingly calm in some places and times, with empty subways, uncrowded landmark areas, and very late-night mobility that makes the city feel usable around the clock. At the same time, people talk about a city that has changed fast: old neighborhoods, street life, and parts of the international social scene have thinned out, leaving a place that feels more polished, more local, and less carefree than before.

Common complaints
  • Scams and predatory social scenes5
  • Foreign-language friction4
  • Smoky or rough taxis / transport hassles4
  • Cooling expat and international business ecosystem3
  • Loss of old neighborhoods and street life3
Common praises
  • Extreme convenience and cheap transport6
  • Food variety and quality5
  • Visual drama and architecture5
  • Safety and walkability at odd hours4
  • City energy mixed with calm pockets4

“The subway ride is less than $1 and so as uber rides. Very strange considering sky high real estate prices and income level.”

“Not as foreign tourist friendly. Cabs smell like smoke and drivers are angry. Literally had one yelling at me because my ride was priced cheaply. Be nicer to foreign visitors maybe?”

Food & nightlife

Greater Tehran
Food

Tehran’s food scene is broad and highly practical: kebab shops, tahchin, stew houses, sandwich counters, bakeries, and endless tea-and-cafe stops sit alongside more contemporary restaurants and upscale dining. Many residents eat a mix of home cooking and quick neighborhood meals, but there is real variety if you know where to look, including regional Iranian dishes, fast food, and street snacks. Eating out is also shaped by inflation, so people often talk about finding good value as much as finding good flavor.

Nightlife

Nightlife in Tehran is constrained by law and social rules, so it does not look like a conventional late-night party city. Instead, social life often shifts to private homes, family gatherings, cafes, restaurants, and informal hangouts, with younger residents making the most of limited public options. When people talk about going out, they usually mean evening walks, cafe time, dessert spots, or meeting friends quietly rather than clubbing in the usual sense.

Shanghai
Food

The food scene comes across as broad, convenient, and very good if you know where to look. Posts mention cheap everyday meals, late-night snacks, and easy access to delivery, while others rave about more polished dining experiences near the Bund and in central districts. At the same time, Shanghai is not portrayed as a place where language barriers disappear: reading menus can be a problem, and some of the most satisfying food appears to come from local spots that are not especially tourist-friendly. Overall it sounds like a city where food is both a daily utility and a serious pleasure, ranging from humble street-adjacent eats to high-end, theatrical restaurant experiences.

Nightlife

Nightlife sounds lively but somewhat changed from its peak years. Long-time residents describe a club scene that used to run very late and feel exciting, even with periodic raids and tension, while newer posts are thinner on a big, open party culture and more focused on bars, meetups, and occasional live music. The city still has a reputation for being able to go out late, but the tone is less carefree and more cautious, with scams and overcharging showing up in the social scene. In practice, nightlife seems strongest in central areas and among people already plugged into local networks.

Weather vs. what locals say

Greater Tehran
By the numbers

How locals feel

On paper, Tehran’s climate can look appealing because it has distinct seasons and dry air much of the year, with hot summers, cold winters, and mountain views. Locals, though, usually describe the weather through discomfort: summer heat, winter cold, and above all the pollution that turns otherwise ordinary days gray and unhealthy. The basin geography means weather is often discussed together with smog, visibility, and whether the mountains are even visible from the city.

Shanghai
By the numbers

How locals feel

People describe Shanghai’s weather as more oppressive than romantic: hot, humid summers, rain that can be nonstop, and frequent comments about how the conditions affect walking around and crowd levels. There is also appreciation for the city’s atmosphere after rain or at sunrise, when the light and emptier streets can make it feel beautiful. In other words, the weather is not praised as pleasant in a neutral, year-round sense, but it is often treated as something that sharpens the city’s moods and photography-friendly moments. The stats may say it is a major coastal metropolis, but locals and visitors seem to remember the humidity, storms, and seasonal discomfort first.
