Is "spotty success" the spin for "mostly failure"? Sorry but there's nobody there, ever. Montgomery Inn gets some traffic but that's about it.
I think the reality is, had they built these up against 161 with parking behind the stores, they'd do better. You'd be able to see what's there. Plus, it would have continued the urban/new urban consistency that they've established in the historic area just a few hundred feet to the west.
Right now, it's a maze just to drive into the parking lot. They even built steps up what looks like an artificial hill just to keep people who do walk over there, out.
Basically, this strip fell victim to Dublin's late 90s/early 2000s suburban zoning codes because it's built like all of their strip malls over on Perimeter. The developer probably wouldn't have been allowed to built the strip in a new urbanist style anyway because the area falls just outside the historic district.
It's sad to say, but it will struggle for a decade or two before it's razed to put in what should have went there in the first place. Dublin is planning on redoing the Riverside / 161 interchange as part of the Bridge Street corridor and I imagine they'll eventually incorporate that strip(once the decision-makers behind this blunder are retired or gone). What a waste. I do feel bad for the business-owners over there. They're probably paying a premium too.
