Neum is not a hot nightlife destination--it attracts mainly Bosnian families, and while Bosnian Muslims drink for the most part, drinking tends to take place in seaside grills-cum-bars, a number of cafe-ice cream-bar type places, and one venue just north of the Hotel Sunce which plays house music and has a flashing light.
What Neum lacks in variety it makes up for in price--250ml beers like Karlovacko tend to cost 2-3 KM depending on the venue, and 330ml and draft half liters tend to be 3-4 KM.
