I look into the crafting guide, and see that smoked fish/meat have +6/5 joy, respectively. However, in the [E]at menu, they are both shown as having 0 joy. Heating them up also results in 0 joy food.
What is going on?
In general, music gives +30 morale. Eating +12 joy hot deluxe sandwiches only sends focus towards 134 or so (on top of music). Drinking fancy hobo (+20 joy) apparently sends it to 150. There does not seem to be any logical logic behind the logic of joy. Short of drinking fancy hobo, you can forget about getting above 130 focus equilibrium. Most of the food effects are poor and fairly short-lived at about 90 minutes at most.
