For a fast food shake, Burguesa Burger's are pretty solid. They're made with hand-dipped ice cream so they're nice and thick, and every one comes with a mini doughnut hugging the straw. [Photo: Burguesa Burger]

Chip's Old Fashioned Hamburgers also serves up some legit old fashioned shakes. They're made with Blue Bell ice cream, and the very tasty banana version has fresh banana blended into it. (If that's too healthy, the Oreo is also solid.) [Photo: Chip's/Facebook]

This Galleria-area shop is known for bubble tea, but you can also get various flavors of milkshakes with the chewy tapioca pearls suspended in them. The green tea flavor is refreshing and not overly sweet. [Photo: Fat Straws/Facebook]

Three words: Banana pudding milkshake. It comes appropriately crowned with a tower of whipped cream and crumbled vanilla wafers, and pairs quite nicely with the ridiculous chicken-fried, gravy-topped burger. (Just don't tell your cardiologist.) [Photo: Garrett Hall/EDFW]

The classic shakes at Highland Park Pharmacy taste like childhood, topped with whipped cream and a maraschino cherry. The butterscotch version is something you won't find many other places, and you can also turn any shake into a malt for an extra 20 cents. [Photo: Google Maps]

Liberty Burger makes several different flavors of mighty fine shakes, but the standout is the sea salt caramel. Topped off with whipped cream, a cherry, and a drizzle of caramel sauce, the sweet-salty balance is perfection. (We wouldn't kick the Nutella graham cracker flavor out of bed, either.)

Even if you're not vegan or lactose intolerant, the milkshakes at Spiral Diner are thick, rich, and delicious. Try the unique Martha the Librarian shake, made with chocolate "ice cream," bananas, strawberries, and peanut butter. [Photo: Spiral Diner/Facebook]

The shakes at cupcake sensation Sprinkles' sister shop are on the pricey side, but all the ice creams are made in house from super-premium ingredients. The pistachio (made with pistachio, not almond like cheaper ice creams) makes a helluva shake, or try a red velvet shake with an entire cupcake blended into it. Hey, we never said it was low-calorie.

Wild About Harry's will turn any flavor of their extra-rich frozen custard into a milkshake. The chocolate shakes here are much less sweet than the typical version made with chocolate syrup; have them throw some sprinkles on top for good measure. [Photo: Wild About Harry's/Facebook]
