I actually think that's regulated by state... In WA there's actually some words in the RCW that say - Nothing shall prohibit "A licensed distiller, domestic brewery, microbrewery, domestic winery, or a lessee of a licensed domestic brewer, microbrewery, or domestic winery, from being licensed as a spirits, beer, and wine restaurant..." And then there are a whole bunch of rules about being a spirits, wine and beer restaurant....
