I was Catholic and single. I didn't feel uncomfortable not being LDS, but it definitely leaves you feeling isolated at times. And the liquor thing isn't really a problem...if you want a drink, you'll find one. If you have a family, the schools are very good. You may detect some religious elements to the curriculum.
I agree with whoever said the LDS who wears the holy undergarment will likely get promoted before you. This is something to consider.
And one last thing. If you go, even if it's just to visit, you MUST go to La Caille, perhaps the BEST restaurant I've every been to (this from one who's lived all over the country). It's relatively expensive, but take my word, you don't want to miss it. The food is marvelous (get the lamb). But it's the setting that will enchant you. It's nestled up against the mountains on acres of ponds and vineyards . It's like a big private estate. You enter through a large gate, then wander through the woods on a cobblestone drive. The building is a lovely French country chateau for which the owner actually imported ceilings, staircases, etc from old French castles. There are little fireplaces everywhere. When they decorate for the Holidays it will take your breath away. On the other hand, when we dined on the terrace in summer, you could look up and see peacocks strutting on the thatched roof. And the service!...they treat you like visiting royalty. It's incredibly romantic and an experience you will cherish. I was fortunate to have a job which required entertaining, so I got to go there often...lucky me!
Let us know what you decide.
I was born in Provo, but my dad was transferred to California, but we moved back when I was 13, and I've lived here pretty much since then. I do like living in Utah and I am LDS. I work for a major software company in Provo, and I'd say it is 60% non-Mormon. I just got out of a team meeting, there are only two Mormons in the group. It hasn't been my experience that the Mormon always gets the promotion, but I am sure that it does happen.
We are very family oriented as a people. I'm single, which can be very interesting at times. I do have a friend who grew up as a non-Mormon, and some of the mothers in the neighborhood would not let her play with their children. That attitude is truly unfortunate.
The Catholic church is very strong here. Religion is very important here, and most Utahans are church-goers, regardless of what religion they are. SLC is 40% Mormon (the last time I heard), so is pretty diverse. You can find whatever you want in SLC, both good and bad. Liquor stores aren't open on Sunday, but there isn't any problem getting liquor or a drink. We have a major NBA team (the Utah Jazz, even though they stink this year), lots of college football and basketball, a symphony, opera, plays, etc. Plus the outdoor life is spectacular. You can drive for 20 minutes and be out in the boonies in the mountains or the desert. The skiing is some of the best on earth, the hiking is great, mountain biking is fun, there is fishing, hunting. Down south, there are many national parks, such as Zion's, Bryce Canyon, Lake Powell, etc.
I love living here, I love to go on vacation, but when I return, I am returning home.
If you have any more questions, let me know freedom, I'd be glad to answer them.
