5/5 Stars - Highly recommend for kids and families! I brought my daughter to Cosmo Nail Salon for her first real manicure/pedicure experience, and we had an absolutely wonderful time thanks to Taylor! Taylor was incredibly patient, gentle, and engaging with my daughter the entire appointment. She took the time to explain each step in a fun way, asked about her favorite colors, and made sure she was comfortable--no rushing, no discomfort. The salon itself is clean, bright, and welcoming, with a nice vibe that didn't feel overwhelming. Taylor did a beautiful job on the nails--perfect shape, smooth application, and cute designs that my daughter is still showing off days later. They held up really well too! If you're looking for a nail tech who's great with kids (or just someone skilled and kind in general), Taylor at Cosmo Nail Salon is the one to book. We'll definitely be back--thank you, Taylor, for making it such a special outing for my girl! read more

For a $85 pedicure and a $15 up charge for gel I'd think I'd leave without dead skin still on my feet... I don't feel like I'm asking for too much.. My nail design was quoted at an additional $60 dollars so I simplified to the same design did the same thing on 6 nails. The pricing is expensive but I was expecting it to be good. The design was to look like a shell but the 3D lines clear lines ran together and the nail tech cured it and was happy with the way it looks... I'm not sure I paid an additional $30 for a really poorly executed design. I'm overall just super unhappy with the look and my experience. I was pressured into up charges for colors and designs which I finally spoke up for myself and changed but I'm super unhappy with what was to be celebration nails.. they just do not look good- and now I'm fixing my own feet which was the whole reason I went for a pedicure. read more

I had a very disappointing experience at this nail salon. I paid a high price for my nails, which I didn't mind because when you pay that much, you expect quality work and good customer service. Unfortunately, two of my nails popped off the very next day, which should never happen after a professional service. When I called to have it fixed, I was met with attitude and no willingness to help. I even spoke to the manager, and he refused to fix the issue and was also rude. On top of that, the staff made me feel very uncomfortable. It felt like they were talking negatively while working on my nails, which is very unprofessional. I came in expecting a clean, beautiful set that would last at least a few weeks, but it didn't even last a day. It was also very expensive, which makes the experience even more frustrating. For those prices, you should receive both quality work and respectful customer service--unfortunately, this place offers neither. There were three of us, and we all left disappointed. I would not recommend this salon to anyone looking for good service or long-lasting nails. read more

Nail service went fine, but for whatever reason the OPI gel color that I selected was not correctly applied. There are lots of areas where there is no color which looks awful and I'll unfortunately have to get them re-done. Not a great experience for the money. read more

Went once I was told I was getting an experienced person. They had been there three months not very good crappy nails. I'm gonna go with one of the girls that has great recommendations. She does not work on weekends. I've seen that the good people are not there on weekends so call find out who they are. Do not let them talk you into people that they say oh is great and they have had no experience. read more

I've getting my nails done at Cosmo for over a year! They are all super friendly and nice! This time I got my nails done with Ivy and she is absolutely the best! She is so attentive to details and she is the sweetest! The best manicure I've have had in a long time! read more

I hate to leave a negative review, but I gave this place multiple chances to make things right. I paid around $200, which is already very overpriced for what I received. My toes were just regular polish (not gel), yet I was charged almost double what is normal, with no clear explanation. The quality did not match the price at all. The nails were uneven, the finish was not clean, and within a short time they started coming off. I also asked for a natural color on both my hands and toes, but they came out completely different my toes turned pink while my hands were a different shade. I was not the only unhappy customer there were three of us together, and all three of us had issues. One of my friends had three nails come off, and instead of properly fixing them, she was told to keep them and come back during the weekday. Expecting someone to go to work with missing nails is completely unprofessional. In another case, when a nail came off, the front desk staff simply put glue on it and said "this is normal, it's okay." That is not a proper or hygienic fix. I called multiple times and gave them many chances to fix the issue. I even said if they don't want to redo it, they can just refund my money but they refused. When I contacted the salon, I was told to come only during weekday working hours, which is not possible for me. When I called again, I was told I would have to pay again. Another staff member simply said, "it is what it is." Charging premium prices should come with premium quality and service neither was provided. Very disappointing experience, and I would not recommend this place. read more

The people were very friendly, however I have never gotten a pedicure for $107 dollars without tip and it look this bad, no attention to detail at all unfortunately! My toes were chipped , gel polish cured all over my skin, and I was cut with the nail file, very disappointed with the service. read more

I just wanted a quick manicure for the weekend and my regular place was booked, so I went online and found this place. I hadn't been here before, but I thought I'd give it a shot. Hannah was my technician and she gave me (honestly) the best manicure I've had in years. Their salon is really nice and clean which is important to me, but the best part is their pricing, a big bang for your buck. This is my new spot. read more

Service was great and the quality of my nails turned out great. I recommend my girl Mona

Do yourself a favor and check out this nail salon! I highly recommend Cosmo as a cute and reliable nail option. For starters, the owner is absolutely professional and friendly, creating a great vibe inside. I came out obsessed with my valentine edition nails. I prefer gel and am in the process of growing out my nails but after Bridget finished my nails look amazing. Plus they do a fabulous job with acrylics like my friend got. I highly recommend this for any locals in Newport Beach or anyone visiting the area. read more

This is my favorite go to place for a mani/pedi and wax. The staff are incredibly friendly, everything is wonderfully clean, no wait (with reservation). The quality of the mani/pedi's is wonderful. Always look forward to going! Thanks especially to Taylor and Mona today :-) read more

Elaine is that girl, she's amazing and so friendly. I was a walk in and had to wait on a busy Saturday but it was worth it! Elaine did a great job and did not rush my pedicure and constantly checked in with me on what I liked/didn't like. Definitely found my new nail tech! read more

Elaine does an amazing job with gel x manicures, making the nails very flat, like a real nail.

Gel pedicure is great, salon is a bit pricey but thats just Irvine. Service is meh. Employees are rude and biased towards certain customers. Very clean and orderly though. I will keep coming back for the quality read more

Amazing as always! Mina did a fantastic job!! Great setting and great customer service!

Made an appt for 5:00 2 hours before and had to wait 40 minutes for them to start. Also slightly rude service and extremely understaffed.

BEWARE!! Absolutely awful!! I paid a lot for a mani/pedi & ended up with chipped nails & thick messed up toes.. I'm a single mom with a busy work/life schedule, & paid for a sitter to get my nails done (which is rare)! This is what $120+ tip gets you.. read more

I did not expect to be dissatisfied, given the amount of great reviews & the location. The nail tech cut 4 of my nail cuticles & made me bleed, when i mentioned it to her she quickly lied and said that I already had those. She was very quick to blame me & afterwards her demeanor for the rest of the service was poor & not gentle. She also started shaping my nails and assumed I wanted whatever she had in mind rather than asking. Disappointed & I will not be returning, there are plenty of other nail salons that host happy, gentle nail techs that are more client & service caring ! read more

Real massage, great nail/foot care and the polish looks good! A bit pricey, but worth it!

Mona does my nails and always does a great job! She's very nice to talk to and I will always go to her.

Wendy did a great job on my nails today! They look so beautiful! Cosmo Nail Bar has a great atmosphere and it is always so nice going there. This is probably close to my tenth time coming here, and I have no complaints. read more

I am so disappointed in this place. It used to be my go-to nail spot! The last time I went, they botched my nails big time, and kept me THREE & A HALF HOURS trying to fix them ?? Needless to say I swore off the place for a while... but tonight I have an important birthday dinner to go to, and really needed a last minute fill... so I decided to give them another try. I'll give them two stars for taking me on short notice and doing the job (relatively) quickly (an hour and fifteen), but they botched me again!! I mean come on y'all... even the woman next to me was disappointed in her nails as well and was on the verge of tears. I used to recommend everyone come to this place, but unfortunately this will be my last hoo-rah. I am sitting in the parking lot fresh out of the salon baffled that for some reason I paid $70 for this. (See photos). I'm sad to see this happen to them. I hope they can turn the quality around... but I will not be going back to find out. ): read more

Clean salon, great service, project runway posing on the tv was a major plus. Miley and Annie helped me out today. Miley did a French tip with dip on my hands, Annie did the same but with gel on my toes. Both took great attention to detail. I'm so happy my friend recommended me to come here! read more

Came here to take my best friend to de stress. Beautiful place with very attentive staff. They had appointments lined up but made the effort to take my friend and I together for a pedicure and a mani/pedi gel despite the fact. The prices are pretty good I'd say for the whole thing and they took very good care of us. I highly recommend for a small little relaxing time. Thank you guys so much for helping her relax :) read more

Cosmo Nail Bar - Express Pedicure 35 dollars - Nail Salons Near Me - Newport Beach, California

This is my all time favorite nail salon! The staff are professional and friendly but they are especially excellent in the services they provide with the technicians all having multiple years in the business. Always a clean salon and a warm atmosphere the salon works to perfection due to Kelly at the front desk. She always greets you by name, comes around to be sure all is good, prioritizes the customer comfort and satisfaction. This is rare in nail salons where you are not felt to be valued but thanks to Kelly I always feel welcomed and appreciated. Their pricing is fair and services are exceptional. It's the best feeling to go to a quality nail salon where you feel like family and are treated very well. Thank you Kelly for always being warm and engaging. You are a wonderful asset to Cosmo Bar Newport Beach!! read more

Amazing, highly professional salon. Stumbled across this place by accident and now I won't go anywhere else. I drive all the way out from Irvine to get pedicures and manicures here. The staff is always so welcoming and solicitous, and they do excellent, careful work. The salon itself is impeccably clean and nicely designed. What really sets this place apart is the attention to customer satisfaction. They are always willing to make room for me even on a walk in basis and always check with me repeatedly to make sure I am happy with the services. No hard upsells, just graciousness. So relaxing and so nice to be taken care of! My nails have never looked better, and they last so long without chipping! If you're looking for a place to treat yourself, this is it. read more
