The Eparchy of Van Nuys website lists 19 parishes. 3 have Vespers, 1 has Vesperal Liturgy.
St. Stephen Pro-cathedral, Phoenix, AZ: Vesperal Liturgy
St. Thomas, Gilbert, AZ: Vespers
Holy Angels, San Diego, CA: Vespers
Our Lady of Pepetual Help, Albuquerque, NM: Vespers and Matins
The list is clearly incomplete. St. Gabriel has weekly Vesperal Liturgy on Saturday, and Matins on first and third Sundays.

My wife and I left St. Thomas last October when the current pastor began canvassing for congregational interest in switching to vesperal liturgies on Saturday evenings. He didn't do it right away, but began during Lent.
(We had many reasons for leaving, not just that one. The RDL wasn't one of them, however. Recently I was asked by a Byzantine cantor friend about changes in liturgies within the Orthodox Church. :)) I smiled at the question, because in the past 100 years the only significant changes for many have been the adoption of the modified Julian calendar, and changing from a church language to the vernacular- both of which do not tamper with the liturgy itself really, unless you focus on things like "deliver us from evil" versus "from the evil one", or debts and debtors versus trespasses. No inclusive language, either. There are some churches that no longer have the Ektenia for the Catechumens, but that's about it, and there is no groundswell to make any other changes as far as I know.)
