Peel and devein shrimp, and give them a quick rinse to get rid of any unwanted grit. Heat oil in deep fry pan.

Mix all ingredients for batter except cola until you are completely ready to fry. Stir cola with whisk to rid of any lumps as fast as you can. If batter is too thin add more flour, if too thick add more cola. It all depends on preference. I prefer a thicker batter.

Fry shrimp, flipping once, until golden, about 8 minutes. Dry on paper towel.

Mix all ingredients for lime sauce.

Serve shrimp on tortillas topped with lettuce, tomato, radish, onion and lime sauce.
