Dempsey Hill, historically housed a former British Army Barrack and later, as Singapore's Central Manpower base, is being redeveloped to be the latest hip area to be watched out for. Akin to Holland V & Rochester Park, the hill houses many resturants, cafe, pubs etc.
One particular to mention is the recent addition called " House". It is a one-stop spa, bar & cafe. If you like to enjoy the benefits of wholesome pampering away from the hustle and bustle of the city, House provides you the comfort. A bit on the steep end, but the sort of pampering on such lush greenery and tranquility is worth every dime.
