I was attracted to The Milkshake Factory by its appealing store-front -- though newly remodeled, it is reminiscent of a turn-of-the-century soda fountain; it's an oasis of quaint charm among the brash bars and restaurants nearby.
The milkshake comes in many flavors, though they are pretty traditional. Happily, what they lack in creativity they make up in quality. The freshly-made shake is thick and satisfying.
They also sell an assortment of chocolates and truffles by Edward Marc. The price, at about $20 per pound, is not cheap, though not unreasonable for those who fancy themselves "chocolatiers." The EM chocolates are dainty in size, but the taste is rich and creamy though for me, the presence of salt is too pronounced. I did not uniformly like all the flavor combination (e.g., the cherry cordial is a bit too syrupy and recalls children's cough meds), but the basic chocolate was well made.
Bonus: the people who work there are extremely helpful.
