Fatburger added two options to bring both sweet and tangy to their already diverse menu. Fatburger will be offering the Reese’s Peanut Butter Milkshake and the Thousand Island Fatburger through March 31, 2014.

The Reese’s Peanut Butter Milkshake provides fans with a blended shake to sweeten up any meal. The milkshake will satisfy any peanut butter–lover’s desires. The Thousand Island Fatburger is returning due to popular demand. Smothered with Thousand Island dressing, this Fatburger adds variety to the savory Fatburger menu. Guests can pair their creamy shake or burger option with crispy “Fat Fries” or hand-battered onion rings to complete the meal experience.

“The Thousand Island Fatburger with the Reese’s Peanut Butter Milkshake makes the tastiest combination,” said CEO of Fatburger, Andy Wiederhorn. “We are always looking to create delicious selections for our loyal customers and know that these menu items will be well received.”
