Did Whataburger. Ordered the #5 with grilled onions & grilled jalapeno...
Positive: The patty was nice. Good char. Good size, good taste. Definitely solid. The ability to add grilled onions and grilled jalapeno is nice. I particularly liked the jalapeno. I couldn't really identify any grilled onion in there, but that might be that I prefer fresh onion anyway which are stronger flavor... Also, the fries were decent (which compared to InO, "decent" is an upgrade).
Negative: OMG could the bacon suck any more? It was the typical fast food paper-thin bacon. What's the goddamn point? Leave it off if you're going to serve me that crap. Also, the tomatoes were paltry. The lettuce was chopped pretty small and not really crunchy or appetizing at all. But the biggest issue was the construction. It was FLAT. I unwrapped it from the paper, and I could have sworn someone put a 5# brick on the damn thing before it came out.
Honestly, I was unimpressed. In a comparison to InO, I would say that the size of the patty makes the Double Double the better comparison, but even with Texas prices, a Whataburger (not the #5) is $5.99 while I believe a Double Double runs $5.65 in SoCal, a much more expensive location. And on the DD, you get an extra [thick] slice of cheese, a big slice of fresh cold tomato, a sizable amount of crunchy lettuce, as well as spread. And it's on a butter-toasted bun that isn't compressed by a boot under Andre the Giant before it's served to you. If you want pickles, grilled onions, or yellow peppers, all are available for free just like Whataburger.
So... It wasn't a bad burger. Honestly there were some good things there--although I'd never ever order it with bacon again. I'd put it equal to above the general fast food chains.
But it ain't no %&*#^% In n Out.
