Does this Mall have a train or place area like the Main Place Mall in Santa Ana has?

No train but it does have a small play area

City of Brea train yes

No. South Coast Plaza put this mall to shame and Main Place. S.C.PLAZA is a high-end mall. Yet does have other stores. It a treat to just visit. I have shopped there for many, many years.

Unfortunately it's not like Santa Ana's mall
