The mackerel had red pepper flakes that gave it some heat, but it was balanced by the coolness of the cucumber slices and shredded carrots. The sandwiches are on toasted rolls, which maintain their firmness but are not too crunchy. They use a chili mayo, which left a spicy tang on my tongue for 5-10 minutes after eating. Excellent sandwich. It costs $7.75 but was worth it.
