Thanks for all the recommendations, folks. I ended up attending liturgy at Holy Virigin Joy of All Who Sorrow Cathedral, the one where St. John the Wonderworker's relics are housed.
It was a very positive experience! The inside of the temple was stunningly beautiful. I venerated the relics of St. John, so that was another positive. Not incredibly huge numbers of congregants by any means, but the ones who were there venerated the numerous icons placed throughout the temple with great intensity. Honestly, in the Greek Orthodox, Antiochian Orthodox, Ukrainian Catholic and Melkite parishes that I've been to, I've never seen many people venerate icons (not much, anyway). But it was constant here. Is that typical of Russian churches (this was a temple of the Russian Church in Exile)?
I did make one minor faux-pas, however. I received the antidoron at the end of the liturgy and then afterwards saw a sign in the narthex saying that non-Orthodox weren't allowed to receive blessed bread, blessed oil, etc. I am allowed to in the Greek parish near where I go to school and have been at every other Orthodox church I've ever attended so it didn't even cross my mind to ask and make sure. Whoops.
Oh, and the choir was great! Right on target.
On a side note, I had settled on attending an Armenian church for Sunday morning, but I called St. Gregory the Illuminator and could never get a time for liturgy with the recorded message. However, I looked on the website of the Armenian Archdiocese in the West (or whatever it's called - the point being it's the archdiocese's website for the western U.S. and lists all the parishes therein), but to my surprise this Armenian church isn't listed! They have another one listed in San Francisco, St. John Etchmiadzin, but not St. Gregory the Illuminator.
But the latter even has a website: stgregorysf.org
But the schedule of liturgy isn't on there, and I cannot understand if this church is or isn't connected to the Armenian archdiocese. Anyone have any idea?
My family went to Glide Memorial United Methodist Church while I was at liturgy. Ah well!
