I am trying to weigh whether it is worth the 2TS or not. If they have free dining again this year then it won't matter too much to us, but if not I do not want to feel cheated.
If you consider using two paid DDP credits for a two-course meal at California Grill being 'cheated', then, likely, that restaurant will be a bad choice for you.
Went there last week - you get an entree, non alcoholic drink, dessert. Same as everywhere else. Only you can decide if it's worth it for you, but for us it was not.
For us, the best part of dining at Ca Grill are the appetizers and the wine. Neither will be included in your plan. I would not eat here if I had to miss out on those appetizers.
