On weekends during the colder months, a Japanese gal sets up outside Mitsuwa's side entrance to grill sweet potatoes and purple yams (about $6 per pound; a tuber for two will run $4 or so). Traditionally, she explained, they'd be baked amid hot stones, but this Okinawan strain, now farmed in Hawaii, was prepared "Jamaican style…like they cook the chicken."
