When we were there in September, we got 2 items and a drink at the Main Street Bakery for one counter service credit.
Actually, my DS only wanted the French Toast Loaf and a drink, and the CM said we could use 2 snack credits for those (one each) instead of a CS credit, so we did it that way. We ended up with an extra CS credit, which we used at the end of our trip to buy some lunch at the AS Movies food court to take with us to the airport.
