So, so good. I have no idea what the other people are talking about. I'm Chinese, from New York (Queens), and this is the best Chinese I've had in Cleveland. I haven't had any food delivered, only takeout, so I can't speak to the delivery service but OMG, the food is delicious. Excellent, excellent, takeout.
Their pepper steak is freaking phenomenal. I was sooo sad when I finished it (btw, the portions are great--I'm just a glutton). The orange chicken was crispy and juicy and awesome. I'd say their sushi is mediocre but it's China Sea, and they do Chinese food right. And at lunch special prices, there's really no reason not to go at least once a week.
I'll go back again sometime this week and try more dishes but I'm pretty confident they'll still get 5 stars.
