Where is a good place in Boston to have a bachelorette party dinner?

I am throwing my sister's bachelorette party and I'm looking for a place to eat that is not too fancy/upscale but has cl. NOT having the usual male stripper/pole dancing cl type of bachelorette party....this is a little more refined. We will first be having a private wine tasting, then moving on to dinner and I would love to find a place that can accommte 10-12 women for around $30 each.
