Ex Input:
I would not order these K-cups again.  Maybe I'm spoiled with Godiva hot chocolate, but I think Swiss Miss hot chocolate has more chocolately flavor than these K-cups and I wouldn't waste my money on these.  It comes out a pinkish color that is not appetizing at all.

Ex Input:
Sure, I could have gone on a food crusade at the local grocery to find a similar product. But I don't think I would have found a product as good and tasty as Dr. McDougall. The noodles are quick and easy to prepare and above all else tasty enough to satisfy my appetite. I was surprised that there were enough peanuts in every bite just like at a Thai food restaurant. Overall, I'm pleased with my order and the quality of the product.
