About 85% of reviewers praise Paninaro Gràcia for its delicious, creative focaccias, fresh Italian ingredients, generous portions, and unique flavor combinations, with many highlighting the mortadella, burrata, and pistachio options as standouts. Roughly 80% mention the friendly, attentive staff and cozy atmosphere, with extras like complimentary olives or chips while waiting, though several note that seating (high tables and stools) can be uncomfortable. The venue is described as stylish, modern, and relaxed, accommodating longer visits compared to other panini-focused spots, but about 10% cite slow or inconsistent service, especially during busy times or regarding order communication. About 10–15% express concerns over price-to-portion ratio (“slightly expensive for what I had”), while a few reviews (about 5%) report negative experiences: two cite serious hygiene and service issues, and one complains about unreliable opening hours. Additional positive details include vegetarian options, Italian drinks and desserts like cannoli, takeaway deli products, and occasional live music.
