Mia (vegetarian) is overjoyed!
If you ever visit Kyoto, do not miss Shizenha Restaurant Obanzai... an all-vegetarian, all-scrumptiously-deliciously-fantastic (and I say that as a fairly avid meat-eater) buffet style ("Viking Style", as the Japanese would say) joint. Obanzai ryori, where this place gets it's name from, is the traditional Kyoto-style home-cooked cuisine... and one meal at this fine establishment gives you an extremely delicious impression of it on your taste-buds!!
Lunch (11am-2pm) 840 yen. Dinner (5-9pm, last order 8:30) 2100 yen. It's a short walk northwest of the Karasuma-oike train station.
