Reasonably high opinion of them. Of course we rarely purchase them, since Mama's brand pork-flavored noodles cost the same, require the same short cooking time, but are spicy and taste sooooooo much better and are more nutritious.
I eat 'Mama' in a favorite street restaurant in the big city an hour from here - it has the traditional mama noodles, but in a 'tom yum' soup, and with many many meats in it. The tom-yum is similar to the broth you're eating but I think richer and more sour, and you can add sugar, fish sauce, and a great fresh minced-peppers-in-oil preparation, as well as vinegar (this last I don't add). The meats on offer (I always get all of them) include stewed chicken feet, chicken balls, two kinds of sliced fish sausage, a sliced sweet pork sausage, incredibly delicous kind of pork-rib things, and some other things I can't remember. Its really a smorgasbord in a bowl, for 40 baht, so about $1.33. They even serve you free iced 'tea-water' - so much more delicious than regular water.
