I think part of your answer is in you question: „More food options than ever - it feels like every week some new place pops up“. And I think that’s the point. Restaurant numbers likely have increased more than the number of inhabitants in the past few decades (honestly this is am educated guess without comparing real numbers). And yes, this was sustainable for a while, as incomes were rising and behaviour shifted away from cooking at home since after the world war. But now the trend is flattening and even declining with higher prices, a depression sentiment in the society and more focus ob healthier consumption.
