We recently had a small work gathering at Deja Brew (
http://www.deja-brew.com/) in Shrewsbury and I wanted to let you all know that it was a very cool experience.
As a former home brewer, it was a better experience having professional grade equipment and having all the ingredients available instead of trying to do this at one's house. The people who run the place are very knowledgeable and friendly and it is a very relaxed atmosphere. Besides having fun brewing the beer, you can sample whatever they have on tap, plus whatever people donate from their brewing.
They have over 60 recipes across all the major beer types and you can also go with one of your own if you like. Depending on the ingredients required for your recipe, a batch of 70 22oz bottles runs between $125-300.
While it is not cheap, I think the prices are very fair and will gladly go back again.
We brewed six different recipes for this outing and so far, the two I have tried have been very good.

Highly recommended.
