Disclaimer: I am not an O-ah jian expert. In fact, I can't even remember when I last had one - I know I must have had one before, but I can't say for sure I've had one in the last decade.
That said, I really, really liked the O-ah jian at Ju Ju Shine. I've read paens to the sliminess of O-ah jian, and... eww. I do not like sliminess. This O-ah jian is not slimy. It has supple and silky segments, from the potato starch or tapioca starch or whatever it is that cuts the egg, but no sliminess. There's a generous amount of baby bok choy and scallion, along with the oysters, and the whole mess has a nice touch of char/wok hay. The thin slick of sauce on top is sweet and gingery and tasted exactly like the sauce from an okonomiyaki stand I love in NYC.
The rest of the dishes we tried were very homey - braised pork belly and soy sauce on rice, a platter of more red-cooked pork belly, pickled cucumbers, and stif-fried cabbage with carrot; a soup with tasty, fluffy minced fish balls but excessively salty broth. The pork belly was a little tough, and the flavor too heavily dominated by soy sauce. Dad enjoyed the O-ah jian, Mom was unimpressed by the meal in general (she found the sauce on the O-ah jian too sweet).
The room is, quite frankly, hideous, with two clashing shades of green duking it out on the walls, a shelf of Japanese DVDs and manga next to the door, and scattered tchotkes (some religious, some cats) giving it a distinctively "Summer at Grandma's House in Taiwan" vibe.
