Those all serve alcohol and their main component is food or music, not an accompaniment to socializing (when was the last time you went to a restaurant to socialize with people you didn’t already know?). The concept is a place to gather that doesn’t have the vice of alcohol but still has an element to inspire social interaction. Without the addition of alcohol for entertainment and to loosen inhibitions, bars are generally boring. Something with rotating themes might work well. Open mic nights (poems, comedy, acoustic guitar), food truck Fridays, taco Tuesdays, etc, would add an element besides non-alcoholic beverages. Hell, people might even love a booze free sports “bar”.
