I moved to Easton a few years ago, and have previously lived in the DC area where the Asian affairs were outstanding, I was quite disappointed with the offers in the Lehigh Valley. I was pleasantly surprised when Sogo opened, and have been there semi regularly (3-4 times per month). I would consider myself a Chinese and Japanese food expert since I grew up in Asia and have Japanese relatives and visited Japan numerous times (and the fact that my family owned a restaurant until my dad retired).
I generally do takeouts at Sogo since I have small children (too much hassel to eat out), and we have had good quality food from them. I have only dined in a few times with my colleagues during lunch, and service then were good.

Their sushi is pretty decent (for Americanized sushi), but not good as my Mom’s (but again she had training with Japanese sushi chefs). I generally order a variety of sushi rolls, my daughters (7 & 4) likes the shrimp tempura rolls and the crab rolls. My husband and I generally rotate between several of their speciality rolls, my personal taste tend to lean towards those with salmon, tuna and/or eel.

I can’t say much about the non-Japanese dishes because we don’t usually order those. I did notice that their hot and sour soup had tasted different from their earlier days, I believe this is due to personnel changes in the kitchen.

All in all, I have been happy with their sushi, this does not guaranteed that you will since everyone’s taste buds is slightly different. For me, I enjoy their food because their sushi is probably the closest to my Mom’s flavoring (i.e. type of sushi rice used, and amount of vinegar and sugar added to their sushi rice).
