What locals say

Synthesized from upvoted comments on each city's subreddit.
Kolkata Metropolitan Area

Kolkata Metropolitan Area feels lived-in, old, and intensely human: a place where colonial-era buildings, dense neighborhoods, and constant street activity shape everyday routines. The city is often described as culturally rich and intellectually animated, with strong pride in literature, art, politics, and neighborhood identity. Daily life can be noisy, crowded, and administratively frustrating, but many people also find it unusually affordable and socially warm compared with other major Indian metros. If you want polished infrastructure and fast-moving corporate-city efficiency, it can be a slog; if you want character, conversation, and a strong sense of place, it has a lot of it.

  • Infrastructure and civic maintenance4
  • Heat, humidity, and monsoon discomfort3
  • Slow pace of bureaucracy and services3
  • Crowding and noise3

Nanjing

Nanjing comes across as a big, historically important city that is still easy to move through if you know the metro and the main districts. Daily life seems to revolve around university neighborhoods, coffee shops, language exchanges, and practical errands rather than a huge foreigner scene. People mention good food, pleasant places to bike and wander, and a city that can feel welcoming if you plug into student or expat circles. At the same time, newcomers often say it can be harder to make English-speaking friends here than in some other Chinese cities, and summer heat is a real drag.

Common complaints
  • Hard to build an English-speaking social circle8
  • Summer heat2
  • Foreign-friendly nightlife is limited or scattered3
  • Short-term housing near campuses can be difficult2
  • Dealing with incidents requires evidence and local know-how1
Common praises
  • Friendly locals and openness to language exchange9
  • Strong university and student presence7
  • Good food and coffee spots6
  • Walkable, bike-friendly exploration4
  • Historical and scenic places5

Food & nightlife

Kolkata Metropolitan Area
Food

Kolkata’s food scene is one of its biggest draws and is deeply woven into daily life. You can eat very well on modest budgets, from kathi rolls, telebhaja, ghugni, phuchka, and cutlets to fish curries, biryani, and an enormous sweets culture built around rosogolla, sandesh, mishti doi, and neighborhood confectioners. The best part for many residents is not just the famous dishes but the density of small eateries, street stalls, and old sweet shops that make grabbing a proper meal feel easy and local. It is a city where food is social, habitual, and often tied to specific neighborhoods rather than trendy destination dining alone.

Nightlife

Nightlife in Kolkata is generally more low-key than in India’s flashier metro scenes, but it does exist in pockets. Expect bars, pubs, cafes, restaurants, live music venues, and late-night food spots clustered in areas like Park Street, Southern Avenue, Salt Lake, and parts of New Town, with the social vibe often centered on conversations rather than clubbing. The city is usually described as having an after-hours culture that is more about dinners, adda, and cultural events than all-night party districts. On weekdays it can feel sleepy outside those zones, though festivals and special events can make the city feel lively late into the evening.

Nanjing
Food

The food scene in the Reddit sample feels practical, varied, and neighborhood-based rather than flashy. People ask for budget places, local Chinese food with beer, and even an Iranian restaurant, while one commenter singles out Commune’s Thai salted egg yolk wings as unusually good. Coffee and casual drinks also come up often, which suggests a city where eating out is part of everyday social life. The overall impression is that you can eat well, especially around universities and expat-friendly areas, but you may need local tips to find the best spots.

Nightlife

Nightlife seems modest but usable, with a few known bars and a small foreigner hangout network rather than a huge club scene. One commenter recommends Secco on a Friday night, and others ask about the go-to laowai bar or weekend events like BBQs and magic shows at Finnegans Wake. The vibe appears more after-work beer, live music, and social meetups than late-night spectacle. For many people, nightlife in Nanjing seems tied to meeting friends, language exchange, or a mixed local-international crowd.

Weather vs. what locals say

Kolkata Metropolitan Area
By the numbers

How locals feel

On paper, the climate is simply hot, humid, and monsoon-prone for much of the year; in lived experience, residents tend to describe it as sticky, exhausting, and sometimes physically draining. Summer heat and humidity can make even short trips uncomfortable, while heavy rains can bring waterlogging and a feeling that the city briefly loses momentum. Winter is often the relief season, with many people enjoying the cooler months as the time when the city becomes easiest to live in. So while statistics may show a manageable tropical climate, locals usually talk about weather in terms of discomfort, timing, and how much it affects commute and mood.

Nanjing
By the numbers

How locals feel

The weather sentiment is mixed but tilted negative in summer. The city can look beautiful in cherry blossom season, and people clearly enjoy outdoor exploring, biking, and photo walks, but one comment bluntly notes that July and August are not ideal because it gets too hot. That suggests locals and visitors appreciate the seasons, yet summer humidity and heat are memorable enough to affect travel planning. The vibe is that Nanjing’s weather is best enjoyed in spring and autumn, while midsummer is something to endure.
