asked one of the staff what juice he would recommend if i felt the flu bug kicking in and he suggested apple+kiwi (amazing how fruit stall owners know exactly what you need...) . tasted delicious. can't remember the exact price, but it should have been less than hkd20.
unfortunately, i passed by the store another evening and saw a staff member smoking outside, but still well within the fruit display area, adding to the smoke from passing traffic.
for those who cook, there's an organic veggie/fruit store across the road (which sells eggs though).
Cons: store faces passing traffic, staff member smoking within stall
