Yep, that's it in a nutshell. A friend and I ate at a Whataburger outside Corpus Christi and loved it. When we got back to San Antonio we told our wives about it -- they were attending a conference -- so we went to a Whataburger there the next day. Not nearly as good.
Been a whataburger fan since 90 when moved to tx. Still my favorite chain burger but I believe they did take a step down with the buyout. I don’t eat fast food as much these days so my assessment may be off.
