The Portuguese Way is not a standard LEA (Linden Endowment for the Arts) art installation. The creators describe it as "a realistic sim, depicting real life Portuguese landmarks and at the same time, show our history and culture, hopefully breaking the stereotype that Portugal is all about sun and sea."
I found The Portuguese Way to be half art and half "virtual world fair" in orientation, and full of fun turns which make it a high recommended place to visit. It is not going to be around forever, and I recommend you visit it before it closes, which will be at some point in the next several weeks.
