I went here the last time I was in Vegas. It didn't help my poker game at all, but it did make me feel like less of a heathen.
Anyways, the patrons of this church with a bit odd, but that could be a characteristic of church goers in Vegas, I only went here, so a sampling set of n=1 usually results in unreliable statistics.
The bonus of this church is the 5pm Sunday service. So I can sleep in, work on alleviating the hang over and still be to church on time (it's a Catholic church, so that means 5:15pm).
The weekend masses are
Sat. 2:30, 4:00, 5:30
Sun 8:00, 9:30, 11:00, 12:30, 5:00
