A few places is not the same as the market as a whole. Regarding your example: yes, you can order some tofu for 23元 but you will need three such dishes for one person to feel sated and such places have minimum order sizes for delivery that typically exceed 2 dishes. (So at your example place, 3 x 25元 average dish price = 75元 per head, plus delivery fee) PS. Downtown Shenzhen is called Futian (福田; "abundant fields") not Putien (which is not even Pinyin, suggesting you are an overseas Chinese person or foreigner with little mainland exposure). I have been based here for most of the last 18 years.
