I live down the street from DLUX and have been there a few times... and always had a great experience. Every time I've gone it's always been incredibly busy, which I think is a good sign for any restaurant. I am obsessed with the red velvet cake milkshake, so rich and tasty. I've never ordered it with alcohol but now that I know it's an option I'll have to try it out :) The Standard (sub chix) is my favorite sandwich on the menu!
The atmosphere is very beautiful and staff is really helpful! :)
