Not op nor do I know which laws you are thinking of.

But, while I was in Utah for a ~week I saw plenty of (probably tourist) people be very surprised that there was a big distinction between the bar area and restaurant area of restaurants as those seated in the restaurant area _must_ purchase food if they're having alcohol.

From what I've heard instead of bars you have to go to "member only clubs" to get around the blue laws. I think they shut down liquor sales pretty early in the evening as well. It has been awhile since the subject came up with my relatives from Utah, but mostly because people don't want them to get started. They are also a state with a fair number of dry counties I believe.

Part time Utah resident here: you can only buy liquor/beer/wine > 5% ABV at state owned liquor stores and restaurants/bars draft beer has to be < 5% ABV but for some reason canned beer can be > 5% at restaurants (Makes zero sense to me). I believe there is like a 1 drink limit max per person at a time (maybe just liquor, I forget) and the state owned liquor stores are closed on Sunday too.
