Thanks. They could break off pieces from the bread wheel in the little street shops where they went for lunch for fish, wine, etc. `Beehive’ like ovens?
The surviving restaurants have holes in the counters, as if they had open fires, or fished the cooked items off coals inside the structure. Might have been bowls.
Here’s an indoor restaurant from ancient Ostia, the menu (like fast food places today) of their most popular products is made into a mosaic on the wall above the counter. People might not be able to read, so the pictures made it easy enough, they’d pay, they’d get their food. Nice shot of it here:
