So those of you who have one of these almost certainly know that restaurants add an 18% gratuity on automatically if you use the Tables in Wonderland card. I always forget that it's 18% off the original price of the food, so if service was average you're pretty much good to go. You can add on more if they were good. (I have to confess that on this trip at the first restaurant I forgot they auto-added it and so I gave a REALLY good tip by accident. She was a really good waitress so I left a really good tip BEFORE the 18% was added, so she was probably pretty happy.)
What is lame is that some restaurants don't do this. I went to Wolfgang Puck's tonight and the 18% wasn't added automatically. I was sitting there with my sliderule trying to make sure, because our waiter was mediocre at best, but I certainly didn't want to leave him nothing. So definitely check at every restaurant.
