I went to get a french mani and pedi in May 2010. The pedi was great, but the mani was terrible. I thought my 7 year old niece had did my nails. I honestly could have did a better job at home. I went back and the staff was really nice about fixing it, but they continually referenced the length of my natural nails while doing so and it was not in English. I would not call it rude, but it was definitely not professional. My natural nails are not short, but they are not long either. I have had french manis on my nails with the same length so I know that it is possible to do a good job.
Pros: Convenient, inexpensive
Cons: Not able to do everything.
