It looks like TheMelt is down to 7 grilled cheese stores.
However:
1) Putting a grilled cheese sandwich restaurant in ferociously expensive real estate known for upscale, health-conscious consumers can't be smart (Irvine Spectrum Center?--LOL)
2) The food just wasn't that good. Sorry. They deserve to go out of business.
Just make some specially-designed plates with a QR code target printed on them and the drones won't even need to land, they can just drop the food right on your plate after toasting the sandwich into a more aerodynamic shape...
