I've been going to Haru for years now, and I've been gatekeeping, but Buttercup by Haru is the absolute best, and has been getting better every time I go. Everyone at Buttercups has been so friendly and the vibes are always great. Even though I'm very picky about my nails, they always catch what I want and are always on top of the latest trends. It's not just the design, but I work with my hands, but my nails never chip or crack.
My friends have always asked where | get my nails from, but now you know!

I found this salon on Instagram and decided to give it a try for the first time today—and I’m so glad I did!

Elvis is truly an amazing nail artist. He is incredibly detail-oriented, gentle, precise, and talented. I used to get gel nails regularly in Korea, and after moving to the U.S., I couldn’t find a salon that met my expectations… until now.

Honestly, this was even more meticulous than many of the nail appointments I had in Korea. Thank you so much for taking such great care with every little detail. I absolutely love my nails!

A big thank you as well to the manager for making the booking process so smooth and easy. Everyone was so kind and welcoming.

I recently came here again to get eyelash extensions done with Lanvy, and I was so happy with the results. I’ve been getting eyelash extensions for over 10 years with many different technicians, and Lanvy is definitely one of my favorites. She has a very light hand, works quickly, and the results were beautiful. They also offer a wide variety of options and use high-quality materials for all their services.

I’ve also had my nails done by Haru and Elvis, and they are both amazing as well. Highly recommend!
