What is the largest portion size offered for ribs at Texas Roadhouse?

The largest portion size offered for ribs at Texas Roadhouse is the "Fall-Off-The-Bone Ribs," which are available in both full and half slabs. This option is particularly significant as the full slab represents the maximum serving size available for this type of rib, making it an ideal choice for those looking to enjoy a hearty meal. The "Fall-Off-The-Bone Ribs" are customarily known for their tender meat that easily comes off the bone, contributing to their popularity and appeal.

In contrast, the other options do not equate to the same portion size. The "Baby Back Ribs" are offered in half slabs, which limits their size compared to the full slab of "Fall-Off-The-Bone Ribs." The "Spare Ribs" can only be ordered in full slabs, yet the focus on the alternative types of ribs doesn’t surpass the quantity of the fall-off-the-bone variant. Lastly, the "St. Louis Style Ribs" are typically served in single portions, which makes them the smallest offering. Thus, the correct answer emphasizes the largest serving size tied to the popularity and characteristic tenderness of the "Fall-Off-The-Bone Ribs."
