The Ichibanya shop sells over a hundred varieties of sembei, with exotic flavors like garlic, wasabi, hot pepper, shiso, plum, seaweed and many more. You'll even find shrimp, bonito, cod roe and other seafood surprises. And while a few of the more outlandish variations may seem like novelty items, many of the flavors are actually very good.

Of particular interest to the sembei aficionado is the little charcoal grill up at the front of the shop, where you can watch the final step in the sembei-making process and then sample some fresh sembei hot off the stove.

Individual sembei start at around Y50, and you can grab a basket and load it up with different flavors as you make your way around the shop. If you're having trouble deciding, there are also gift-pack assortments of some of the most popular flavors.

(To get to the shop walk down the side alley that runs parallel just to the right of the main route to Senso-ji Temple; the shop is around 2/3 of the way to the temple, on the right.)
