Deliver a meal to Smitty for Mom.

Deliver a meal to Smitty for Mom is a side quest in Fallout 2.

Walkthrough
Mom can be found inside her diner on the east side of The Den. Talk to her about what's going on in town, and she'll ask you to deliver a meal to Smitty. Agree and head out to the west side.

You'll find Smitty in the junkyard on the far west end, past Lara's gang's house. Give him the meal and he'll trade you a stimpak. If you head back to Mom's, she'll offer you a meal that restores a few hit points. You can decline it and come back later if you're not in need at the moment.
