Have you ever been to an event in a city park or similar where breakfast/brunch is provided/for sale and the price point is $3-10? It's hour old greasy food, hard bagels, and stale donuts. A way to churn out fresh sandwiches / bagels / eggs / etc. on demand would be a game changer. As soon as you're paying over $10 (or really over $6-7) it's hard to imagine a massive benefit from today's robots. But I could definitely see cooking robots dramatically change quality of food available in the $1-9 range, especially in locations without a full kitchen available, and especially breakfast / brunch stuff.
