I am looking for a room rental for my son's 1st birthday party. A place that is in West Allis, New Berlin or Brookfield area. I would like to bring our own food and beverages.
I have found the most cost effective rentals are renting pavilions at the local parks. Alot of them have enclosed, heated halls or party rooms and some even offer fridge and stove. You can also bring in your own food and drinks. Google the Milwaukee and Waukesha County Parks websites and all renting info should be there.
I rented a nice room (with a full kitchen) through the Wauwatosa parks system. It was the building at Hart Park. We hosted my BFF's baby shower there. The room was a nice size, we were able to bring in our own food and drink and had a really nice time.
I think Tosa might be a bit more expensive, but definitely go through the parks! They have nice resources for decent prices.
