I'll echo some of the gripes about bars in Utah. It's incredibly hard to just get inside the bar compared to anywhere else because you have to be a "member" of the "social club" that is the bar to get it. Therefore you have to either go with someone that is a member of the bar or buy a temporary membership just to get in - a little annoying, but I guess that happens everywhere in Utah...?
Inside, the bar wasn't too bad. You can actually get beer stronger than 3.2% as long as you get something not mass produced and brewed elsewhere (I got a Sierra Nevada that had it's normal 5+%) and they had a band playing that wasn't incredible but was pretty good considering I was in a small town in Utah.
Overall, an ok place to hang out. There are some not so great things about it, but it's in a small town Utah so a lot of it couldn't really be helped...
Oh yeah, and it's called Rumor, not sure what the Diamond Lounge stuff is about.
