Never had a Whataburger until it was late last night and I spotted that it was open at 11PM. Ordered a double cheeseburger with grilled onions, cheese (40 cents extra), extra pickles, ketchup and onions. I also ordered a breakfast biscuit with bacon egg and cheese for the morning.
The burger was totally packed and literally fell apart (in a good way). Their bun is not one of those huge fat buns so holding the stuff together is difficult. But I like their flatter bun without the huge dome. Remember, the larger the bun the more calories you consume.
The biscuit was not as good as the competitor's (M). The biscuit needs to be more crumbly, and the combination of flavors just doesn't make it. Even the bacon tastes better at the other place.
I would go back for the burger especially since they are open late!!!
