We had my sister's bridal shower at Isabella's Nail Bar (http://www.isabellanailbar.com/index.php) in Montclair. It's a nice, new nail spa. The experience was "ok" (i.e., nails turned out "ok"). The owners were very nice and accomodating though. In fact, they let us stay a little past closing, and I was even going through contractions at the time and didn't know it! (gave birth the next day). They did _not_ close the spa down though...probably because we didn't have that many people showing up. I'm sure they'd be accommodating though, and you should give them a call. At the end, they gave everyone lavendar sea salts as a favor from them. I still have it and use it. IF you plan on having a baby shower in San Francisco, Tiptoes Nail Spa has just opened, and we're having my friend's baby shower there: http://www.yelp.com/biz/tiptoes---a-nail-spa-for-everyone... Wow! I just checked Yelp and the reviews are great.
