At this totally unremarkable counter with totally sumptuous sushi, dinner times are crowded and fun. A ¥2,500 or ¥3,500 combination gets you soup and up to 10 different kinds of sushi. Nobody here speaks English, but but folks are friendly and helpful; if you're unsated, just point to what looks good. Look for the purple-and-white polka-dot curtain on Yasaka-dori, north of Sanban-cho.
2–6–19 Sanban-cho, Matsuyama, 790-0003, Japan
