A melt-style sandwich is a menu description, not a standard portion. Arby’s Reuben, Culver’s Grilled Reuben Melt and Culver’s Single Sourdough Melt have different recipes and totals. Compare the order you would actually buy rather than treating “melt” as a nutrition category.
Keep like names distinct
Arby’s Reuben lists 680 kcal, 37 g protein and 2,420 mg sodium. Culver’s Grilled Reuben Melt lists 660 kcal, 37 g protein and 1,840 mg. Those two tie on published protein while sodium differs by 580 mg. The 20 kcal difference does not settle that sodium question.
Culver’s Single Sourdough Melt lists 490 kcal, 26 g protein and 600 mg sodium. It is not another Reuben recipe and should not be described as the same sandwich with one ingredient removed.
A practical shortlist
If your example search requires at least 30 g protein, the two Reubens qualify and Sourdough Melt does not. If sodium must also stay at or below 2,000 mg, only the Culver’s Reuben of this trio remains. These demonstration limits explain the decision; they are not a recommendation for your day.
Different sources have different dates
The Culver’s figures come from its linked July 2025 guide, while the Arby’s source carries a June 2026 edition. Both were retrieved in October 2026. A comparison does not make their edition dates equal or certify local availability. Sides, drinks and extra dressing remain outside these sandwich rows.
