I know, I said I don't usually do a Zagat rated restaurant, but this place is different. Five Guys Burgers and Fries has won accolades all over and I'm about to add mine.
This chain started in the DC area a few years back and it is growing fast. It isn't a typical fast food joint as many locations are in an office building, as well as the free-standing ones. They have a successful business model. Do one thing, do it right, and be consistent. They have burgers, dogs, soda and fries. That's it. Nothing complicated, nothing fancy. Just good food served right.
A regular hamburger has two patties and the little hamburger has one. They are all cooked well done for safety reasons, and to make the operation simpler. This way when the order is placed it's simply a matter of how many patties they have to make. Then you can add any of fifteen toppings, ketchup, mustard, peppers, onions (grilled or raw), etc, plus the cheese and bacon if you ordered that. Sodas are large and regular, as are the fries. The fries come or Five Guys Style, or Cajun. Regular or large. Regular size is plenty enough for two people to share.
We've been to the Poughkeepsie location twice now, and found it to be great both times. You place the order and they tell you your order number (it's on the receipt too) and the approximate wait time, and have a seat. On the way you can pick up some roasted peanuts in the shell to pass the time. Five minutes or so later, and they call your number. Each order is cooked fresh. I usually get the little burger as I'd rather have two of them than a single regular burger. The burger is good too.
Stop by at your local Five Guys for a nice burger. Check out the website to find one.
Update 12/19/08- I went here with seven people who have never been to a Five Guys before and they were impressed. We had all been at a party, and ate there, but we managed to chow down pretty well. I ate two burgers and even though I was stuffed, I could have had another. These are probably the best 'fast food' burgers out there.
