Imam Mahdi Association of Marjaeya

If you want the authentic experience. Look no further. This is the place. While not a traditional masjid, it does offer a prayer hall. This is actually the local office of Grand Ayatollah Sistani. One of the foremost figures in Shia Islam. You can't get any more authentic then this. Look up sheik Rizwan if you get a chance, he really is gear lt shining example of the best Islam. I do all my learning by him...
