[Now, I was checking out the website of russianchurchusa.org this evening, and was looking at some of the parish listings, where I noticed that the cathedral in NY actually conducts liturgy in Russian!]
I have a very good friend who just moved to Dallas, Texas and is attending the OCA Cathedral there (St Seraphim's).
He has nothing but praise for the Cathedral and their cycle of services. If I understood him correctly, they have Vespers every day and Liturgies throughout the week. Since there are three priests they serve entire Liturgies in English, Church Slavonic, Serbian, and modern Russian.
