    Tips with dip that lasted over 4 weeks!
    Morgan B.

    I got these tips with dip 4 weeks ago today!! I have never had tips last this long. Not a single nail has chipped, broken, or popped off! I bite my nails and have nubs, so the tips barely even had anything to glue to. Amazing job by Cosmos!!!

    Out of all the nail salons on 18th street, and maybe all of DC, this is my new favorite nail salon! The first two times I came as a walk in to get a gel mani. I had no qualms and was very happy with how my nails looked and no chipping issues - very long lasting. The last two times I saw Kim and got liquid gel. She likes doing designs and so I just let her do her thing. It takes about an hour to prep and put on extensions and another half hour for the polish and design, so make sure you account for the time! Love coming here and I will be back.

    I do not know how this salon has averaged four stars. I just moved to the area and had tried a few salons, and this is the worst of them all. The people were very nice and I really wanted to like them but this is just unacceptable, especially for the price. Not featured in the photos is a cracked nail on the left hand (it doesn't photograph well). I've never felt more ripped off in my life. For $100 with tip, I have a literal crap manicure where I regret even getting them done and a smudged pedicure. I'm trying to go back to get them fixed, stay tuned if they charge me ... I wouldn't be surprised. They were booked the last day so I couldn't go in. Oof. And after I wrote that review, another has chipped -- my thumb. Photo posted. And now my left index is chipped (day 4)

    Obsessed with this place!!! Amazing prices amazing staff

    I have been a loyal customer of Cosmo Nail Bar for nearly two years and these past two years I have had the most polished appearance I have ever had. This place is truly a gem and you must treat yo self to the experience. Located on the main strip of Adams Morgan, Cosmo is anything but off the beaten path. The salon is one of those bigger on the inside kind of places that has a large back room to accommodate extra foot traffic (pun intended as the back room is for pedicures). There is also a large area for manicures. The place operates like a high efficiency beehive and I have never had to wait for more than 5-10 minutes for a WALK IN! Amazing, right?! Now I always stick with the classic pedicure, and I will sometimes add on a classic manicure if the moonlight strikes me. I'm fancy, but not that fancy. The classic pedicure only costs $28. That's it. A BARGAIN. During the week they have happy hour specials and it's even cheaper! Now I was first wary of such a low priced pedicure, but I have NEVER been disappointed. They do a fantastic job every time. They don't cut corners, just nails. They also go above and beyond to scrub your lower legs with a sugar scrub, lotion them with a nice green tea lotion, and then massage them with hot stones. It's almost unbelievable that you get all that for the most basic pedicure they offer. You can pick any polish color off their wall or bring in your own as well. Manicures are a pretty similar experience, and if you add one on, it will cost about $50 total. Woah. Attention‼ They offer you complimentary wine while you're enjoying your salon experience. They have red, white, and house made sangria to choose from. If I recall correctly, they have had champagne in the past on occasion. Overall, I highly highly recommend Cosmo Nail Bar. It's such an Adam's Morgan gem!

    I went in to get a full new acrylic set to fix a sloppy manicure from a different salon. I am SO impressed with the service i received! Tweety was my technician and she was extremely patient & informative. She paid very close attention to detail. The shape is perfect, they even look great from the side! I truly wish I could give even more stars!!

    Uju O.

    Every time I'm at Cosmo's, I receive exceptional service. The ladies are very friendly and attentive. The manager, Yoyo usually takes care of me, and she knows exactly how I like my nails. I would suggest making a reservation since business fluctuates, and you may not always get the nail tech you want, otherwise. Make sure you are open to the ladies switching on and off as there are ladies who specialize in different areas! Definitely check out their new location at 1911 9th Street NW, as well!!

    Highly recommend pedicure services from here!…read more While I was out taking care of errands, I looked up on yelp some nearby nail shops, in hopes of getting a serious spa pedicure, and that's when I came across the incredibly high reviews of Famous Nails Spa. I called them to see if I can come in the next 10 mins for a pedicure, and they took me without issue. I was warmly welcomed when I walked in and asked to sign in, and then I walked back to the pedicure chairs. My nail techinician, who didn't introduce herself and was not particularly warm towards me, greeted me and got down to business. Now-I warned her that my feet were in a rough condition, so I didn't mind her being all business because these toes needed THE business. The pedicure service was fantastic!! my feet were scrubbed and rubbed, my toes nails cut and shaped, and my polish was summertime ready. My nail technician offered me water towards the end of my service, which I graciously accepted, however I noticed most people were offered a beverage at the beginning of their service. The spa is relatively cozy in size and efficient, no frills or luxury, but everything was tidy, and my pedicure was done amazingly, and completed in a bit over an hour. I checked out efficiently and was given a somewhat short and dry good bye..hahahaha. But honestly, their service speaks for itself. I definitely would visit here again, and beware of the limited street parking.. prices are reasonable too!

My technician was nice, but seemed to really want to get me in and out of her chair as quickly as possible. I have never kept my hands under the UV light for less than 60 seconds per layer, but at one point I timed it and my hand was under the light for 15 seconds. It was truly: finish one hand, immediately change hands to put under the light. I questioned it internally but figured she knew what she was doing. I got my nails done on a Tuesday, by Sunday one of my nails was chipped. Bliss has a policy that any chips within 10 days can be fixed for free, so I went in the next Wednesday to get the nail fixed. Again it was incredibly rushed, 15 seconds max under the light. By Friday the nail chipped again. Two days later another nail chipped. Less than two weeks and the manicure was already chipping. A disappointing experience compared to my first time there.

The nail technician (male) who worked on my naturally healthy nails did a poor job. The process took much longer than necessary, and without my request, he applied gel builder, which I didn't want or need. Typically, my gel manicures last at least three weeks without any issues at all, but this one barely made it a week before breaking and chipping. The finish was also noticeably bumpy, far from the smooth, polished look I expect from a professional manicure. I've attached photos to show the subpar results. While the ambiance and staff friendliness were highlights, the quality of the gel manicure itself was a huge letdown.

I had to ask them to leave it like that without the final step because I came back home to file down my nails and shape them and add gel and everything. I went there because I wasn't going to have time to do them on my own because of travel. It was horrible and then on top of that he cut my real nail off after I told him they were mine and then I had to ask for him to add a tip nail to it because he was going to leave it like that when he messed up. I paid $61 for this shitty service. Waste of money and time since he took almost two hours.
