You can add DG to the list of hotels that have cleaned up well in the wake of the downtown revitalization.
What used to be the Lady Luck is now a totally re-modeled boutique style hotel. Like the Plaza and Golden Nugget, Downtown Grand really illustrates how the redevelopment of downtown is moving along nicely. During the remodel they chose to keep alot of the exposed steel girders and brick facades giving the casino a industrial look. DG has a nice chic feel to it and they definitely didn't cheap out on the hotel rooms. The rooms have been completely updated and have a sleek modern touch to them; for the ~$50 they charge, its a great deal.
The casino itself is pretty small, there are a few bars and small restaurants littered throughout. From what I saw, the prices on drinks and food were very reasonable. It looks like Downtown Grand relies alot on Triple George Grill and the like just outside to really satisfy diners. Overall DG is a great edition to Downtown and 3rd, its nice to see DTLV on the up and up.
Tip: Downtown Grand doesn't have a parking garage, valet only. Remember to bring your dollars!
