Unfortunately for that situation, there are far fewer tourists on the north coast these days. The focus on the north coast is buidling condos and villas for expats and some snowbirds.Many tourists like to enjoy something familiar when in a different country...not for every meal, but on occasion. And, many will splurge a bit, whereas they might not go to one "back home." This Hard Rock Cafe can fit that desire. If they are depending on a big percentage of repeat local customers, that could be a struggle.
Expats and long stay snowbirds might go once to the HRC, but probably will get their burgers elsewhere from what I have seen of the prices and situation at an HRC.
The vast majority of tourists, those who stay less than a month, go to other parts of the DR due to the expensive and limited flights to Puerto Plata airport.
