The BEST Nail Salon in Burlington?

I live in Westford and sorely disappointed with all our nail salon options. I’ll be in Burlington (mall area) tomorrow for work and would love to get an amazing manicure. Usually go for dip/ powder. Open to a different kind, but regular polish is a waste! Any tried and true recommendations for somewhere clean, kind and pampering? Either right in the mall area or in a neighboring town. Thanks so much!
