In the season 5 episode "Tree Trippers" the gang goes to Eric Roberts house to get some shrooms so they can find an answer on if Vince should do the Benji movie or Smoke Jumpers. The house that the gang visits Eric Roberts is in real life known as the Iny Estate. After doing some research I also found out that it was used as Steve Sanders house in Beverly Hills, 90210 among many other Hollywood projects. It is a massive house having 15 rooms and 6 bedrooms. There is a gym, library, media room, an elevator, and 4 fireplaces among many other amenities.
