There is a place called the Dairy Keen which has what my family calls the train burger. Me and my family have been going there for years. It has a good bacon cheeseburger and all other burgers.
They have the best shakes and fries to dip in them :) DELICIOUS. It has the Heber Valley railroad lined along the ceiling where there is a small train that actually runs along the top.
It has great service and has cool pictures of things around Utah. This is a great family-friendly restaurant if you are looking for a good sit inside or eat out night. :)
