Actually, the last few times I checked the list, this place was set to leave the program after July. I can't check it right now because the website is down. Both of our observations make sense, though. If you checked it on Sunday, then naturally it showed up as the only day available as it is the last day of July.
Edit:
BTW, I've been to Blind Faith Cafe, and I agree that it's pretty good, even for us nonvegatarians. The I went there, though, I didn't know it was in the program so I missed out on free miles.

This reminds me of a funny story. A friend of mine used to go to Blind Faith weekly with his then fiance (ex-fiance now). She was vegetarian and loved that place; he isn't and hates the food there. His solution was that he'd stop at Subway and buy a sandwich. Then, they'd go sit at Blind Faith and she'd order her food. When her food came, he'd open his Subway sandwich and eat it there with her. I was amazed at the fact that they let him do this, and that he actually would do this. He responded to my amazement by saying, "What were they going to say? We ate there every week. If they had said something, we would have just stopped eating there."
