The thing about restaurants and blenders is that not every restaurant uses the same blender, and they use the one that best suits their needs. For instance, in one restaurant, they might use a Blendtec blender, but in the one across the street, they might use a Vitamix or a Hamilton Beach one. Yes, one brand may be more famous than the other, but what most restaurants really use are different commercial blenders that they choose depending on their cost, performance, durability, size, and noise.
