Tag for a hut that occasionally offers food for hikers?

There are some mountain huts or tourist farms, for example, that occasionally have food/beverage offer for hikers on random days - whenever they please.

Is there a tag for such huts/farms to indicate that they may offer food, rather than tagging them as alpine huts (which would be misleading)?

Restaurant with an appropriate opening_hours maybe? (Such as “seasonal” or “irregular”)

At an alpine hut I would expect lodging too, restaurant makes clear that isn’t the case here
