This isn't exaggerating - service sucked balls all but 1 time that I've been there. Guessing that was only because the guy who cooks (the owner?) helped us instead of the awful Japanese waitresses. They probably just hired them because they speak Japanese regardless of experience but I've seen the same ones working for over 2 years. They've never gotten any better.
Shuseki's food is great, its my fav place for ramen because of their variety. Love tan tan and the karubi ramen. Lol had to say karubi out loud to realize they were phonetically spelling kalbi spoken w a Japanese accent.
I continue to go back despite the bad service but here was the worst experience I've had with them. My friend and I both ordered ramen, he got his within 10 min and I sat and waited for mine. Waited 15 additional minutes till I flagged her over and asked about my food. She gave me a blank look said she'll check on it. My friend shared some of his while we waited for another 10-15 min and I just gave up and told her cancel it and bring us the check. Mind you there were only 3 other tables of people, so the kitchen and waitress werent at all busy. When she brought the check, she apologized and said - don't leave tip. No worries honey, you weren't getting one anyway.
No explanation as to wtf happened, but I left there pretty pissed and with good reason.
So like I said great food, just walk in there w incredibly low expectations for service. And stay on her @ss if things don't come out right away.
