In DE, the Dinner is buffed
from recovery of HP from 15% to 20%, and stat is boosted from +1 to +2.
By the way, Dwarven Stew is created by combining Dinner and Beer, but the effect of Dwarven Stew is weaker than Dinner... (only +1 Strength, not +2)
Now in DE:
Dinner +2 Strength, Recover 20% HP per round
Dwarven Stew +1 Strength, Recover 20% HP per round
Elven Stew +2 Fitneese, Recover 20% HP per round
