i just ate whataburger earlier today for lunch,it was good,one of my #1 favorite fast food restaurants in my opinion
I believe their primary difference is the process of Char-broiled meat...making it much less fatty. The also give you choices of what to add or remove with their toppings.
i think we have red robin here too but i never been to it,i heard it's good though and love to try it....Wow, looks pretty good. We have a chain called Red Robin up in this area (near the big cities). Serves some pretty good burgers and never-ending French Fries. MMM-mmmm, good!
whataburger started in texas and spread to few(not all)other states in usa
