And definately go to Squatters brewery (www.squatters.com) and try their specialty beers. Their polygamy ale is very popular and then you can go home with a T-shirt that says "I tried polygamy in Utah" or one like this:
I want that shirt!
...Went to squatters... I don’t drink beer so I had tequila instead...
I remember attending an academic conference in SLC and how annoyed most of the participants were when the refreshments did not include coffee. One of my colleagues was on the planning committee and he told me that the professor in charge of accomodations was from BYU and didn't think that coffee was necessary so he didn't order any. That decision was quickly overruled when the complaints flooded in.
