I thought this was only a Utah thing, but we have this option here:
WAC 314-11-065
What type of liquor is allowed on a licensed premises?
(1) Licensees may only possess and allow persons to consume or possess the type of liquor permitted by the type of liquor license held on the premises; except:
(a) Under authority of a banquet permit (see chapter 314-18 WAC);
(b) Restaurant licensees may allow patrons to bring wine into the premises for consumption with a meal;
Just like UT, they can charge a "corkage fee".
