Way Back In 2015,

KFC opened an all you can eat buffet restaurant in Osaka, Japan,

easy to find with the Colonel outside, and you could go with the free flow beer option, for the rundown have a look at the visit the SoraNews24 made at that time,   

now KFC takes this treat to Tokyo, located at the Minami Machida Grandberry Park, the KFC Restaurant offers a lot of dishes, including the classics such as their original recipe fried chicken, mashed potatoes, and new dishes from their “KFC Special Chicken Menu”, and continues with the free flow beer option, just one slight snag, the crew arrived before the 11.00 am opening time, and were given the ticket to be seated number 124, so 123 sittings before they could be seated, which was 5 hours later! it just does to show how great a deal it is, for a full report on the new all you can eat have a look here, all photographs, SoraNews24.
