You use the word 'lifestyle,' which is a word I hear often in Thailand, especially Bangkok. I see Bangkok lifestyle and culture as superficial and far from interesting. As far as quality of life goes, I think there are other cities in the world that have aesthetics, green spaces and cultural events far superior to Bangkok's lifestyle. If 'lifestyle' refers to certain cars, condos in certain neighborhoods and dining, I see Bangkok as fairly unimaginative. I'm not criticizing your use of the word, but the idea of lifestyle is one of the biggest draws to living successfully in Bangkok.
Maybe you are right, but Thais also refer to 'lifestyle' and it has to do with a high standard of living. So I'm not sure.
Another one bites the dusk!
I bet after it's gone you could hail a cabbie and tell him Nana Plaza and he'd drive to there anyway, without a word.
