**UPDATE*
I guess it really depends on which technician you get, went back again and a lady did my shellac. terrible job, and was chipping the next day.
Dropped in for a $20 shellac manicure and I am quite happy with the results. There are a few negative reviews and perhaps the place was busy when they went but today my experience there was actually quite nice. I got the owner for my manicure and he was pretty thorough with everything (nails shaped well, cleaned cuticles etc). As said in some of the previous reviews, there is a slight language barrier, it was hard to understand what they were saying in english but the owner is fluent in both Mandarin and cantonese so i ended up conversing with them in Chinese.
Overall, it might not be the place for you if you're looking for a classy spa day, but for $20 it was definitely worth it.
