TN Nail & Spa provides friendly and welcoming service, with staff being attentive to customers' needs. However, some clients have reported inconsistent quality of work, with issues such as poorly done nails, sharp edges, and uneven polish application. Despite this, the business offers convenient payment options, including Zelle, and has a reputation for being accommodating to special requests. Overall, TN Nail & Spa offers a decent experience, but may need to improve on the quality of their services.
