Does anyone else think it's a good idea to serve real food for immersion in roleplay

Well, I've said plenty of times the food would be prepared before the game maybe I'd let them know beforehand with a menu handout early on so they could decide if they want to eat anything. I also said that the food and/or drinks would be served during break periods where the character sheets are put a safe distance from the table.

For example before the planning phase fully commences I know that I'm gonna have the party camp with Elves or Half-Elves in Faerun So I create a menu handout with the following from the Heroes' Feast books along with Puncheons and Flagons

Quith-Pa

Elven Bread

Moonshae Seafood Rice

Greenspear Bundles in Bacon

Cherrybread

Elven Marruth

Chopforest

Elven Flatbread

Meal's End

High Harvest Puree

Evermead

Elverquisst

Feywine Punch

and 

Kinship Shrub

I would also have mini explanations of the ingredients so the players know what they want.
