Looks tasty, but if I received that at even a fast casual restaurant, I'd never go back. If I made it for myself at midnight and it tasted good, I'd be real happy. But a packaged sausage on a piece of supermarket sliced bread isn't something I'd pay for at a restaurant. I think it's the relatively clean white plate and symmetry that's giving your friend restaurant vibes, but he should also maybe go to better restaurants.
