Don’t make the same mistake I did. I recommend to purchase directly from Gurn glass website. The small business gets more money and you pay less . Groupon takes a *huge* commission. Oops . (Almost half I believe)
We had a great experience at the Thrill Factory. We enjoyed the quieter atmosphere (than another big entertainment place on the west side of Madison,) and the additional entertainment features (e.g. bowling, mini golf, laser tag, etc)
