"We get so much requests, people get upset" when they're told there's no room, reports Donna, who cooks in front of his guests during the dinner.

What's not changing at the performance space is the price: $85 per person for the dozen-plus courses, which change from month to month. Among the treats he's rehearsing for a future menu: Italian-style profiteroles stuffed with liquid saffron and served with coffee reduction.
