I've been missing the gluttonous excess of the now-closed all-you-can-eat/drink BBQ buffet that I posted about all summer, but perhaps found a kind of replacement: The all-you-can-eat/drink buffet at the Kyoto Royal Hotel, near Kyoto's Sanjo/Kawaramachi intersection.
I heard about it a couple of months ago, but didn't get a chance to try it until recently, to celebrate my father-in-law's birthday. I thought the food was very good, a real bargain at 2,500 yen. Add 500 yen, and you also get the alcohol bar... beer and wine (red/white/plum). Tasty.
It's particularly nice for me because I can walk there in about 20 minutes, so can start to work off the extra calories right away.
(That's just a phrase... I don't actually care about calories, I care about carbs, and generally avoid them.... except beer and wine :-))
