My wife raved about Delux. She said this was the best burger she's had in the area. I finally went with her and by no means was overwhelmed. The burger was fine, but not the BEST I've ever had. 
The burger was not much better than something you might get at Chilis, Red Robin Cheeburger, Cheeburger etc (my opinion). I think I actually would prefer a burger from these places over Delux.

Maybe my expectations for this place and burger were set too high and I was disappointed with the final product.

Pros:
The sweet potato fries and dipping sauce was very good. The service was excellent.

Cons:
Limited seating and basically rubbing shoulders with the person next to you because you are packed in so tight. T the lighting in the bathroom is very dark. I'm shocked techno wasn't being played when I walked in. I didn't like the trendy nightclub feel of this place.
