For Dr. Pepper drinkers out there, beware, the Cheesecake Factory
doesn't serve Dr. Pepper! In fact, the last time we were there and I
kindly asked for it, our waitress pulled an attitude when she said,
"No, we don't have Dr. Pepper." I then kindly asked for regular Coke
(which they do serve) and she gave me diet Coke! I don't really know
what her problem was but it was a bit uncomfortable for the rest of
the meal. Fortunately, we didn't have any issues for the rest of our
visit. So when you go the Cheesecake Factory, don't ask for Dr.
Pepper!

So bring a bottle of your own Dr. Pepper. I seriously doubt your
waitress or the manager will care.
