rabidralph’s advice about partnering with local microbreweries rings true to me (as a consumer). Microbrew fans (like me) will clear their schedule for a tasting night hosted by a local microbrewery. Create some type of frequent visitor rewards program, gather patron email addresses, and send out regular email newsletters (it’s cheap advertising) with announcements, events and digital coupons to keep your place top of mind.
And certainly everything you said about marketing the restaurant through the beer releases, keeping in touch with customers, etc.
