The fast food counter at my local 7-Eleven in Taipei is different. Not different by Taiwan standards – there seems to be a 7-Eleven on nearly every block. But, different by US standards.
They sell tea eggs and sweet potatoes.
Yes, tea eggs.
They fill the entire store with an aroma of black tea leaves, spices, cinnamon, cloves, star anise, fennel and a variety of other spices. There may be some soy sauce. Inconsistent reports on that.
Have not tried yet. Too chicken.
