(This is actually a chain restaurant from japan with branches in taiwan, thailand, and singapore)
i knew the portions are going to be small so i ordered a few dishes:
kimchi pork hot pot set ($85): lots of chinese cabbage, served with an egg and thin slices of pork. not really filling in my opinion for one person. it came with a small bowl of rice and 2 dishes of marinated vegetables (cucumbers in one, lotus root and carrot in the other)
plain udon: i think it is handmade. nicely chewy texture + good broth. had some wakame topping too.
stir fried sweet and sour vinegar pork: apparently this is one of their signature dishes. it was served with a heap of vegetables (not sure what it was, i gave it to my mom)
mushroom hamburger: came with a small amount of potatoes. patty was thick enough; sauce was sweet and paired nicely with the mushrooms. also served with a mix of vegetables on the side.
soymilk with black sugar: i don't have a very sweet tooth and found the sweetness to be just right.
pudding with vanilla ice cream, cake (caramel flavor, i think) and adzuki paste: i adored the red bean paste which came with whole adzuki beans (not mashed!) and i was impressed by the real vanilla ice cream - you can see the vanilla pods in the scoop! the pudding was nicely creamy, not gelatin-like at all which is awesome. didn't try the cake.
i enjoyed all the dishes but will not order the kimchi pork hotpot next time. will try other desserts on the menu and i definitely recommend ootoya. no wonder they are able to expand across asia!
