Try Ryogoku’s Famous Chanko-Nabe
Big eaters will love chanko-nabe ちゃんこ鍋.
The special type of hot pot, or nabe, normally uses a chicken-based broth full of meat, vegetables, and tofu designed specifically to pack pounds onto sumo wrestlers. Despite being calorie-rich, the chanko-nabe is very healthy, often having fish and a variety of greens to balance the high protein content.
Chanko Tomoegata ちゃんこ巴潟 has been in business for about 40 years, and they offer a traditionally Japanese take on chanko-nabe, featuring simply seasoned side dishes to complement the hot pot. You can even get sashimi with your chanko. You certainly won’t leave Ryogoku hungry.
