The Sandwich Board x Complex is a $ American sandwich spot with a strong review signal: 4.6 stars from 277 Google reviews, plus 92 all-time Blackbird check-ins recorded between May 15 and May 18, 2025. Reviewers frame it as a Lower East Side hole-in-the-wall: order at the window, expect limited sidewalk seating, and treat it more like a grab-and-go mission than a lingering meal.
The order that keeps surfacing is the Mala Wrap, praised as flavorful, with crispy shallots singled out by one reviewer, and notably strong value at $10. The duck sandwich and duck tsangwich also get love, though one reviewer flagged the $20 duck sandwich as a bit high for its size.
Blackbird traffic leaned weekend-heavy, with Saturday and Sunday as the busiest check-in days.
