I hate to say it, but SLC feels like a fairly small city. I don't think that is a bad thing, just my perception.
I was just there last weekend for a ski trip, and it doesn't seem like it has changed all that much since I lived there in the early 2000's.
I did like the more dense feel of downtown. The new buildings on State Street definitely make it appear more urban. But, I did a walk around downtown between 3:30 and 5:00 on Friday, and it felt dead (and the weather was decent, even after the big snowstorm).
I did enjoy dinner at Eva, it was very busy. Also went to Ivy & Varley - not so good, but also busy. The SunTrapp was the opposite - pretty dead even at 11pm (I know it was closed for a while with an ownership dispute, that may be a lingering issue).
Here are a few photos of State and Main Streets looking very empty:
