We thought not due to the configuration of the (pretty intimate) space -- there are bars taking up most of the venue's primary walls -- but said it wouldn't be impossible, either. And, guess what? It's not. Because it is happening. O'Sheas will be expanding. But, not into The Quad, into The Linq.
Our @sammasseur dropped into O'Sheas for a drink (or two) last night and talked to a staff member who said the lease for the restaurant that was to flank its other side at The Linq fell through and that O'Sheas would be taking over the space and using the kitchen to provide a full-service restaurant to guests.
Chayo Mexican Kitchen can be found on the west side of O'Sheas at the Linq but we're not certain which restaurant had been planned for the east side. Our source didn't happen to know the answer to that, either. We're thinking it could be The Stomping Grape or Off The Strip, both had been previously announced as Linq tenants, but have gone unmentioned for quite some time now.
As for an opening date, we don't have one right now, but expect an expanded O'Sheas would debut with the remainder of the outdoor mall. That should start next month and run through March.
