Happy Nails & Spa offers excellent quality gel nails that last long. Their nail technicians, including Rachel, are skilled in creating beautiful designs. However, some customers have experienced inconsistent service, with one reviewer feeling overcharged and receiving shoddy work from a technician. They also charge extra for long nails and may not include cuticle care. Prices may vary depending on services booked. Some customers have mixed experiences with the quality of their manicures, while others have been satisfied with their gel polish removal.
