Which Broadway restaurant was known for offering an actor's menu with lower prices?

The choice of Sardi's is an insightful one because this restaurant is historically recognized as a popular dining spot for Broadway actors and theater-goers. Establishing a connection with the entertainment community, Sardi's caters specifically to those in the theater industry. The actor's menu that it offers features lower prices, providing an accessible dining option for those who may be working or involved in productions nearby. This tradition has made Sardi's not only a culinary destination but also a cultural landmark within New York City's theater scene.

The other choices, while notable in their own right, do not have the same strong association with Broadway or the tradition of catering specifically to actors in terms of a specialized menu with discounted prices. Joe Allen, for instance, is also known for its proximity to theaters and has its own charm but does not maintain the same unique actor-centric pricing strategy as Sardi's. Becco offers a renowned Italian dining experience but similarly lacks the specific actor's menu concept. The Olive Garden is a well-known chain that does not have a direct connection to the Broadway theater scene or an actor's menu, making it an unlikely choice in this context.
