They are the same place. Leaving DTD make a left at the crossroads. Its less than 1/4 mile down the road on the left hand side. Its at an intersection, you can see it from the road, its behind a cheesy souvenir shop covered in Red White and blue.
This is the bulding you are looking for.
Millers is a chain, it seems to adopt the name of whatever city it it in. Technically the location near Crossroads is the Lake Buena Vista Ale House, but it says Orlando on the sign outside.
