I'm just gonna do my three active DnD characters, plus my current favorite among my prospective DnD characters (aka the one I'd play if I either were to start a new campaign or if one of my other characters were to die).

Wococo: The aarakocra ranger loves eating game, especially seared deer or boar, with a warm sauce made of berries and served alongside a decent ale, which he usually drinks after his meal is over because he is a drinking lightweight and doesn't enjoy how being drunk lessens the taste of dishes for him.

Worteg: He's from a Dragon Age-based DnD campaign and, while a dwarf, his opinion on traditional dwarven cuisine is very low. His favorite dish is roasted nug, stuffed with fresh herbs and fruit. Nugs are a traditional dwarven meat source but he appreciates it most when prepared in a more Ferelden style like that.

Subtle Flame: My tabaxi rogue is an adventurous eater, seeing regional cuisine as a way to experience different cultures. As a result they tend to order dishes which common folk can afford and which is typical for the people of the area. Flame, despite their name, isn't that big into very spicy food, though, which is why they tend to order milk as their preferred drink to compensate for potential heat in their order. On the road however Flame is an opportunistic eater.

Jarsh: The githzerai monk is a vegetarian and tends to favor simple dishes. I imagine her to mostly prefer soups with bread, ideally whatever the Faerûnian equivalent of broccoli cream soup is, with a nice whole wheat bread to dip it with.
