The Jae's on Boylston is in such a weird basement space and the feng shui is all messed up which may explain why it is never packed when I go there (even though it should be because the food is good and reliable).
I went on Friday night with the GF. The service was perfect. The server was magically there whenever we needed her but we never noticed her otherwise. We started with the seafood pajon and it was good. It may be the best in Boston, but sadly, nowhere near as good as what you can get in NYC. My standard is crispy on the outside (which is done well at Jae's), full of seafood (also good at Jae's) and kind of chewy on the inside (the one I had on Friday was too fluffy). Comparing NYC and Boston seafood pajon is a lot like comparing the pizza of both cities. I think there might be an issue with the water.
I had the soon tubu jigae for my entree (spicy tofu stew with seafood and beef). The flavor was perfect with rice but I think the seafood might have been the pre-fab bags of mixed seafood that Sodexho sells. The GF get a couple of handrolls including this weird deep-fried roll with shrimp and cream cheese. The cream cheese was little overpowering and we probably won't get it again. We loved the salmon-skin roll because the salmon skin was still hot and crispy when we bit into the roll. An important part of the sushi rolls which Jae's nailed is the rice, which was lightly vinegared and not mushy (as is often the case with many sushi joints).
