Do you remember this outdoor picnic table? It too had a well/gutter/trough running down the middle of it. That same idea has now moved inside, and to the kitchen island!
In this case, it looks like the built-in trough holds herbs, wine, and oil and vinegar... which is a bit of an odd grouping, actually. It seems it'd work best when used to store items you want quickly at hand when you're cooking (utensils, oils, spices). I do like the look of the wine bottles sticking out; I'm just not sure of its practicality. Might be great for an informal party, though, with guests milling about and serving themselves.
What do you think of this look? Would you ever do it? Have any other creative ideas for how to make use of a countertop trough?
