Please, disregard my last comment. The module works fine with multiple locations. When I tested with the second and third location, the module didn't work, and I assumed that would be an issue, but the module worked well with all other locations we have, just two of them are not working. On those two locations, when I click "Find a Table", the link takes me to OpenTable site (location is right) instead to open the modal.
Any idea why that would be happening? OpenTable configuration maybe?
