RE: They fixed my favorite beach bar in Da Nang
They did this to a beach bar here in Ao Nang called "The Last Fisherman" and the attempt to be more upmarket didn't attract the richer clientele they were aiming for and they simultaneously pushed away their dedicated budget audience as well. Over the course of two years they were able to lure the budget crowd and the locals back at great expense to themselves. Some times not changing anything is the best business model you can follow.
The idea behind the beanbags is sound, but I agree those are gonna get nasty really quick. I hope they have a plan to clean them.
