If you are running a game set in Ancient Rome, grab this at once! If your game is set in another place or time, it's still worth a look as the dishes presented are exotic enough (yet strangely familiar) to offer up as the height of culinary arts in some remote orbital station in the far future or the capital of a mysterious fantasy kingdom.
There are occasions when it might be politic not to tell diners the precise details of what they are eating. (After seeing my mother's face when I told her what 'calamari' was when eating in Venice, I didn't tell her about the snake a few years later in China...) Of course, evil GMs might tell the players how delicious the meal served to their characters was, and only reveal what was in it later... (and then call for rolls to avoid vomiting!).
Now Mustard Beans (green beans cooked with crushed mustard seed, honey, nuts, and vinegar) served alongside Poached Sole (sole poached in wine and broth) would be a treat for anyone, but one might be a bit more cautious about Sow Womb (pig uterus, udders, and belly are cooked with broth, pepper, and loveage). There's a tendency to eat odd bits of pig, there are several others that I'm not sure I'd fancy, at least, not if I heard what was being served before I'd tried it!
It's these little things that make the alternate reality of your game world come alive: dig in and make use of them!
