Karsen's Grill is a little joint tucked away in the heart of Old Town Scottsdale that makes food that will change your life. The staff is friendly and extremely helpful with navigating this delicious, mouth watering menu that is simple but changes from time to time due to the chef's creative imagination. I had the Southwest Cardiac burger that is now on my top 5 burgers I've had. The choice of ingredients in all of their burgers and sandwiches are perfectly matched and come together like a ballet of flavors that is discribed simply as....perfect. They have a small bar with friendly bartenders that pour nicely. This is a small place with BIG TIME food! A must when you are in the area.
