Q. Is there a mitzva during Chol Hamoed to eat meat and drink wine as there is in Yom Tov?
A. (See question 2146 above) Piskei Teshuvos (530: 5: n. 63-64) quotes Horav M. Feinstein zt’l and Horav Eliashuv zt’l that although there is no obligation, there is on the onset a mitzva to honor Chol Hamoed at least once a day, by eating meat and drinking wine, in order to create simcha and joy.
However, Poskim mention that this mitzva, even on Yom Tov applies only to the ones that actually enjoy it. (See question 1719).
