Good scotch/foreign whisky shops in Dallas?

[MtnDew]

Going to be in Dallas for a week starting this Thursday, any good shops in town for scotch? I plan to swing by a specs just out of curiosity but I figure there has to be some other stores as well. So far in my research I found one specs that has a Glendronach single cask (2209, 20 yo) but the total price is $170 after tax so it's quite spendy. Anything else worth checking out?

Thanks!
