"I've been visiting this restaurant for years, and it has consistently earned a five-star rating from me. However, I do want to mention that portion sizes have been getting smaller each year. I understand they recently opened a new location in Scottsdale, which might be affecting things. Typically, the milkshakes are filled to the brim and topped with whipped cream under a dome lid. Unfortunately, on my latest visit, the milkshake was only three-quarters full, with the remainder being whipped cream. In fact, there wasn't even any whipped cream touching the dome lid. I will continue to come back, but I'm disappointed by the change in portion sizes over the years. The cups remain the same, but the servings do not."
