What locals say

Synthesized from upvoted comments on each city's subreddit.
Greater London Urban Area

Greater London feels like a dense, high-opportunity city where neighborhoods can feel almost like separate towns, each with its own rhythm, price level, and social mix. Day-to-day life is convenient if you can afford it: the transport network, late opening hours, and sheer number of services make it easy to get by without a car, but space is tight and rents are the constant pressure point. The city can feel impersonal at first, yet many people settle into a pattern of local cafés, parks, markets, and commuting routines that make it feel manageable rather than glamorous. It is lively, diverse, and always busy, but the tradeoff is cost, crowds, and the need to be patient with delays, bureaucracy, and the pace of urban life.

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

  • 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 London Urban Area
Food

The food scene is one of London’s strongest everyday advantages: you can find excellent curry houses, Thai, Turkish, West African, Caribbean, Middle Eastern, Chinese, Japanese, Italian, and modern British spots across the city, often within a few stops of each other. Casual eating is especially strong, with takeaways, sandwich shops, market stalls, bakeries, and pub food forming the backbone of routine meals. The main downside is price, since even fairly ordinary meals can be expensive, and the best-known places often require booking or a wait. Still, for variety and access, the city is hard to beat, and many residents build their week around local favorites rather than destination dining.

Nightlife

Nightlife is broad rather than centered on one type of scene: there are pub crawls, late bars, club nights, warehouse events, comedy rooms, music venues, and neighborhood wine bars, depending on where you live. Some areas are energetic and noisy well past midnight, while others become quiet quickly, so the experience is highly local. Transport shapes the culture because people often plan around last trains and night buses, and a night out can feel more like a logistical exercise than in smaller cities. The upside is choice; the downside is that a fun night can get expensive fast.

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 London Urban Area
By the numbers

How locals feel

Statistically, London’s weather is milder and less extreme than many people expect, with few truly harsh winters and summers that are usually not oppressive. Locals, though, often describe it as grey, damp, and disappointingly overcast, with drizzle and low light making the city feel colder than the numbers suggest. The complaint is less about dramatic storms and more about the accumulation of cloudy days, short winter light, and the feeling that rain is always possible. When the sun does come out, people seem to notice immediately, which says a lot about how they experience the climate in practice.

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.
