Im a very big fan of the Tempeh Katsuretsu (Deep Fried Tempeh) plate and the Avocado Enchiladas Plate. Each one of these alone does not fill me up so I always get both. Costs about 2400yen together. I am not a big fan of the white sauce they put on the Enchiladas so I always get it without the white sauce.
I usually get the above. However, once in a while, I go for their "deli plate" which comes with 3 dishes you can choose from approximately 6 offerings. You can see it right in front of you. So if you see 3 that look real appealing, you might want to consider that.
Also, their Tempeh burger is killer.
They sell books by the way with all their recipes (in Japanese).
Cons: pricy for the amount but still worth it., I sometimes wished they had waitresses
