Max and Kelly have a zany aunt who works at the Zoo. When Max's birthday draws near Aunt Zelda sends a birthday card and a family pass to the Zoo Room Restaurant, a place of which the family has never heard. When the family arrives at the Zoo Room - after the Zoo has closed - they discover a strange restaurant filled with animals. It's noisy and exciting - even a bit dangerous - and many things are out of the ordinary. The family has a wonderful night celebrating Max's birthday and the Zoo Room is a restaurant that young children, including Max and Kelly, will never forget.
