I'm glad I wasn't the only one that had some of these concerns. The bar ones weren't available here, but lunch and dinner were and it does say you can go alone, but they do prefer a partner (going alone would really be awkward since they are very stern about do not use your phone except in the smallest ways...I've always thought these days a guy sitting at a table alone not using a phone or computer would draw more attention than anyone else around).
Still, despite it being reimbursement only, I was about to pick one up just because I like Chili's now and then, but I saw the photo requirements, and was ummm, wide angle, overhead,...and umm, just no. I can see me now, going alone to Chili's not using my phone except to take the most odd shots anyone can think of. They will either know I'm up to something or call a psych for me.
