Hamburgers and steakburgers can have a similar taste depending on a few factors. Here are some possibilities:

1. Seasoning: Some restaurants may season their burgers and steakburgers with similar spices and flavors, such as salt, pepper, garlic, onion, and Worcestershire sauce.

2. Patty composition: Some restaurants may use a blend of ground beef, including cuts that are typically used for steak, such as sirloin and rib-eye, to create a more flavorful burger patty.

3. Cooking method: Both hamburgers and steakburgers are often cooked on a grill or griddle, which can impart a similar charred and smoky flavor.

4. Toppings: Many of the toppings commonly used on burgers, such as lettuce, tomato, onion, and pickles, can be used on steakburgers as well, further enhancing their similar taste.
