We are headed to Yosemite on Sunday and have 4 tent cabins. Are there BBQ grills available for cooking? Any information about Curry Village would be appreciated!

I don't remember bbq grills and doubtful there are grills given how crowded the park is in summer and the concern about fires. The "dining" at Curry Village is in a cafeteria style arrangement.

no cooking allowed

Definitely no cooking in Curry Village. The tent cabins have front steps, but they don't really have any patio, picnic table or anything like that. There are "bear boxes" where you put all your toiletries and any snacks that you bring, but there isn't a whole lot of room in the bear boxes, so you should keep any food you bring to a minimum.
