Hirohisa Vending @ Upp Serangoon Shopping Cte is listed as a bar at 756 Upper Serangoon Rd, Serangoon, Singapore, though its name suggests a vending machine outlet. It holds a 4.0 Google rating from 1 review, so the score is a thin guide.
Vending machine outlets sell drinks or snacks from automated machines, so there is no table service and no one to ask for a recommendation, and the experience is quick and self-service. A well-run one keeps its machines stocked, clean and working, and shows prices clearly. If you are looking for a drink in a bar, a venue with staff, seating and a drinks menu will have clear opening hours and an entrance, and it is wise to check recent reviews and a map pin before you travel. Upper Serangoon Road is a long road with a mix of shopping centres, eateries and neighbourhood shops, and a shopping centre unit follows the building's opening hours. Regulars carry coins or a card for machines and check that the unit is open before travelling. With only one review and a name that does not match the type, it helps to look for more recent feedback.
For anyone around Upper Serangoon Road, this entry is best read as a vending outlet, not a bar.
