heytea has a seoul-exclusive drink, at least when i was there in hongdae
it’s a hand-peeled jeju tangerine drink: tangerine pulp sits at the base, topped with a slush of 100% tangerine juice and fragrance-free jasmine green tea, and naturally tinted with beetroot juice.
overall, was pretty good. more of a slushie than the typical heytea drink.

sooyeon had the classic mango pomelo sago, and she thoroughly enjoyed it. was her first time in heytea, and she could not stop admiring how good it was and how appreciatively unsweetened the drink was. i did ask her if she liked it enough to come back again, and she said maybe next year given that the walk was a bit far for her… ps: the walk is only 30 min from campus
