About Kosmo Nail Bar

Kosmo Nail Bar is an aesthetic nail salon that provides a professional and clean environment for its customers. The nail technicians are courteous and attentive, often offering beverages and mocktails/drinks to clients during their appointments. The salon is known for its exceptional service, with customers praising the kindness and expertise of the staff.

One customer, who visited for a Gel X manicure and a gel pedicure, was particularly impressed with the quality of the work and the overall experience. The nail technician recommended a powder gel instead of the Gel X, providing detailed information about the difference between the products. The customer was satisfied with the honest and educational approach, and the final results of both the manicure and pedicure. Customers have also highlighted the salon's cleanliness and organization, noting that the establishment lives up to the quality one would expect for the price.

Reviews mention that the service is amazing, and they truly care about their customers, with no problem adjusting things if you don't like it. The space is very inviting. Another customer was blown away by Betty's service, who went above and beyond making sure nails were like the inspo pic and even stayed after hours. Betty tested each chrome to make sure it reflected the picture and was detailed, taking time to perfect each nail, drying them individually. Kim was also mentioned as a personable, gentle, and detail-oriented tech who assisted with a complex design by asking another nail tech to help. This level of customer service is abundant at Kosmo. The shop is clean and has a very modern spa-like vibe. Customers are highly satisfied and would definitely recommend this place.

Shout to Michelle for an excellent manicure with an incredible attention to detail. She helped achieve my “flashy neutral aesthetic” after two really disappointing experiences at other nail salons in the area. Highly recommend.

The place is clean however the tech I had act as though she didn’t speak English, I couldn’t understand what she was saying. She began to push my hand and moved around awkwardly, and my nails are OK but it’s not really what I want.nor did she offer me anything to drink

I've been going here for two years, never a bad experience! Ask for Joanna, she's the best :) thorough, efficient and professional. Also like the convenience of being able to text for an appointment.
