I finally had a chance to go by and check out the reopened Opera Cafe yesterday. They serve the same desserts and pastries from Opera, and some sandwiches and salads that are slightly different, but still good. The owner, Heidi, is the former manager of Cafe Bassam, so she has some experience in this area. She said they were so busy yesterday at lunch they ran out of focaccia for their panini sandwiches which is good news. (Apparently the cafe closed not for lack of business, but because of a business dispute.)
I just finished a croissant for breakfast, and I still think they're about the best I've ever had.
