Pretty Relax Spa is a nail salon in Bishan, Singapore. Google reviewers rate it 4.6 out of 5, from 123 reviews, a good result for a salon of this kind.
A good nail salon is judged on hygiene and on the care taken with the detail work. Look for tools that are sealed or sterilised in front of you, and a clean, orderly workstation. Ask what the quoted price covers before you agree, since a basic manicure, a gel finish and nail art can add up quite differently. Many people find it helps to bring a photo of the shape and colour they want and to say how long the finish needs to last. Booking ahead is usually sensible, particularly on weekends and before public holidays.
The salon is in Bishan, a residential town in the central north, so it suits people living nearby.
