Kapu is the place to go from Akihabara to satisfy your okonomiyaki craving. To get to it, walk across the Kanda River a few minutes towards Kanda Station. Once you get there, be prepared to wait if you go there during the peak hours; there is often a long queue to get a seat in the restaurant. Kapu only has narrow counter seats and serves Hiroshima-style okonomiyaki. The restaurant has large iron plates in front of the counter where you see the chef prepare the okonomiyaki. That's part of the fun of going there. For 1,200 yen you can get a good size okonomiyaki with some nice toppings and soba noodles as a base. Beer is 550 yen.
Okibariya is located directly to the South of the Akihabara Station. That joint strangely specializes in cakes as well as okonimiyaki. The restaurant is particularly popular for its 600 yen lunch sets! For that price, you get a salad, miso soup, bowl of rice and a good size okonomikyaki. Cream-filled roll cakes are quite popular for dessert. For dinner, expect to pay around 3,000 to 4,000 yen per person if you order a couple of drinks along with your okonomiyaki and side dishes.
Hanako is located near by the Kanda Station. So from Akihabara, head South, cross the bridge and walk for a few minutes to get there. It specializes not just in okonomiyaki, but anything that is cooked on an iron plate (teppanyaki cuisine). It was featured in the 2017 Michelin Guide so the place has a really good reputation. Their okonomiyaki is really outstanding! Served on a piping hot plate, it's made with noodles Hiroshima-style. You might want to try the butter shrimps or hamburg steak while you are there too!
Yukari is located very near the Akihabara Station. It takes just a 3-minute walk to the north of the station to get there. Yukari prides itself on using very fresh, good-quality ingredients for making their okonomiyaki. That explains a lot why so many people flock to this restaurant! Their most popular item is the mix of pork, cuttle fish, shrimp and octopus okonomiyaki at 1,280 yen. You can get many other choices of okonomiyaki but also some yaki soba made on the same iron plate for about 1,000 to 1,200 yen.
Hide is another great okonomiyaki joint located near the Kanda Station, south of Akihabara. It's a popular place to grab a cheap lunch. You can eat there for under 1,000 yen. They serve both okonomiyaki and yakisoba. If you go there for dinner and order plenty of food and a few drinks, expect to pay something around 3,000 to 4,000 yen. You can order beer, cocktails, wine but the best here are the Japanese sake. There are several all-you-can-drink courses ranging in price from about 3,000 to 8,000 yen.
That was a convenient guide to some very nice okonomiyaki joints around the Akihabara area. Enjoy your time in "electric town" and its okonomiyaki!
