We recently tried the new smasher
My wife and I recently tried the new Sonic Smasher, since we just moved to this neighborhood, and there's a Sonic nearby. We used to live in a major metro near a hamburger chain that is well known for its "smashed" burgers. The Sonic burger tasted good, but it was not at all crispy. It was a regular burger in taste and texture. Although it wasn't bad, it is not worth a return visit. It's hard to know if the local grill crew were properly trained. On the other hand, the extra queso we ordered for the tots was particularly vile. It had a chemical taste we found unpleasant. I didn't even offer it to the dog.
