Delux is a definate staple in the Phoenix food scene. This is one of the better establishments in the Phoenix area.
If it is your first time heading to Delux, I would start with the Delux Burger itself. This is a very good burger that is best served the exact way that it is spelled out on the menu...including the medium rare serving temperature. Trust me, I am a medium temperature on my burgers (the only thing that is not red), but the juices that flow through this burger are unbelievable. Start the table off with a basket of mixed fries (sweet potato and regular fries) for every 2/3 people there. Well 2/3 hungry mid-20s men. If you want to venture away from the burgers on the menu, I suggest getting the grilled cheese and adding chicken and bacon to it. The chicken sandwich is pretty good, but the grilled cheese is better.
The restaurant is definitely cool inside, and the patio is nice. This restaurant is busy, but never seems to be longer than a 20 minute wait time. The bar is cool, and a great place to grab a few beers. They always have something new and exciting on tap, so ask for a draft list and enjoy something cool and refreshing.
