I do believe I've been doing this all wrong all my life... And considering how much I do enjoy my ketchup, I think this calls for a trip to a burger joint.
If I were still in Portland, I'd head to a Burgerville (seasonal, local specialties, local meats used, tons of vegetarian options... who doesn't love that?). In Cali, I'd probably run to a Nations and grab the BEST grilled cheese and some fries just to try this out. But out here in Austin, I'm really not sure where the best place to get good quality, but stay on budget (i.e. - not spend over $12 on a burger and fries) is... Any recommendations? :o)
