What locals say

Synthesized from upvoted comments on each city's subreddit.
Jakarta

Jakarta feels like a huge, constantly moving city where convenience and chaos sit side by side. People who like dense urban life praise the malls, food, transit, and the sense that the city is still raw and local rather than fully polished for tourists. The biggest frustrations are predictable: traffic, pollution, flooding, pedestrian-unfriendly streets, and the mental fatigue of getting around for ordinary errands. At the same time, many residents and visitors describe Jakarta as warm, sociable, and full of small pleasures if you can tolerate the friction.

Common complaints
  • Traffic and commuting5
  • Pollution and heat4
  • Lack of walkability and outdoors3
  • Flooding and urban disruption3
  • Social isolation and hard-to-find community3
Common praises
  • Food variety and eating out5
  • Friendly, welcoming people4
  • Big-city energy with local character4
  • Malls, transit, and modern infrastructure4
  • Nightlife and live music2

“At the first glance, Jakarta looks so promising. It has the density, warm climate, low prices, friendly locals, lack of tourists... it could be great, maybe better than Bangkok. However, in daily life, it fails over and over again, in ways which are fundamental and can't be fixed. The air is poison, literally. I get a headache after breathing it for an hour or two. The city is outright pedestrian-hostile, with worst walkability I've seen anywhere. Traffic is infamous, you aren't going anywhere easy.”

“Honestly, I find the city really charming. It has a kind of vibe that’s getting harder to find in Bangkok (which I love) because of overtourism. It’s not very touristy, so the experience feels more local.”

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

“Go to secco on a Friday night.”

07 · Culture

Food & nightlife

Jakarta
Food

Jakarta’s food culture sounds broad, cheap-to-upscale, and deeply woven into daily routines. People mention warungs, kaki lima stalls, mall food courts, seafood, Indonesian comfort dishes, coffee, sambal, durian, and late recovery meals after a night out. Even visitors who were otherwise stressed by the city often single out the food as a major reason to come back. The overall impression is not of one signature cuisine, but of a huge city where you can eat constantly and still keep discovering new places.

Nightlife

Nightlife seems active and social, but not uniformly clubby or glamorous. One post asks for clubs where people actually mingle rather than sitting at tables, which suggests that the scene can feel segmented between open, welcoming venues and more exclusive spots. There are also mentions of live music, bossa nova, and general nightlife being “hot,” so the city clearly has options for people who want to go out, drink, and meet others. Still, it reads more as a practical big-city scene than a single, defined party district.

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

Jakarta
By the numbers

How locals feel

The travel-guide version of Jakarta is hot, polluted, and rainy, and Reddit mostly confirms that—but locals often describe those conditions in more visceral terms. It is not just “humid” or “smoggy”; people talk about headaches from the air, gray haze, heavy rain, flooding, and days that feel physically draining. At the same time, the weather is folded into city identity, so rain, smog, and heat are treated as part of the deal rather than a surprise. Visitors sometimes romanticize the atmosphere, but residents tend to talk about it as one of the city’s main costs.

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.
