Great burgers, great selection of toppings, great selection of sides. Everything is fresh and prepared on the spot: yes, this does increase the wait time and isn't what people expect when they think "fast food," but this is a gourmet burger prepared like you would at home. Better than you would at home, they grind the delicious looking chunk of beef right there in front of you!
The spicy fries (with the spicy mayo) are a great side if you like food with a bit of kick.
