9lives' comment on the Stumped thread below prompted me to write a quick review of the new Jae's, in the spot formerly occupied by 711 Restaurant (which had been on my Restaurant Dead Pool list for a while; I have to say I cheered a little bit when that awful place closed).
A sleek-looking and pretty big basement space, a rich-looking redo of the previously hideously-tacky room. Two bars and a long sushi bar. I've now been for lunch a few times, and it remains what I remember Jae's to always be: slightly expensive, rather Westernized Pan-Asian, with the Korean dishes tending to stand out.
Maybe expensive is the wrong word: my issue is that Jae's serves Western-style, outsized portions. That $14 lunch Bento box would be better at 2/3 the price and 1/3 less food; it's too much for lunch. Also, the bulgoki in one box I got was sliced too thickly and served in oversized pieces. It was tough and chewy, difficult to eat with chopsticks.
The service and atmosphere are the best I've seen in a Jae's; it seems reasonably priced at lunch for a Back Bay place of this level of fanciness. I just wish it were a little more authentic, and a little more restrained on portion size, but this kind of Asian food seems to be their niche, and it least it's no P.F. Chang's.
