Eating at the Muny has evolved considerably. My late husband, Joe Pollack, used to look at the then-newly-installed picnic benches and beam, because he had urged their installation in his column in the Post-Dispatch. This year, they've expanded their casual dining options with Cafe One, for sandwiches, salads and pizzas. I had the open-faced ribeye grinder last night and found it worthwhile, the beef tender and flavorful, the whole thing messy to eat but quite tasty. (And it's huge, if that's a concern.) Last week, I went with friends to the buffet in the Culver Pavilion, and I wrote about it for St. Louis Magazine's blog.
Two things: Parking is easier if you arrive early. If you don't, the Muny is famous for its very punctual 8.15 curtain. I saw people arriving last night at 8.40.
