Half-price sushi is the way to go - for fresh made good rolls and nigiri, this is the place. There are a few others in the area, but none as cheap and unassuming as Wang King. The different puns the name affords are also worth the visit.
Ambiance isn't superb - normal piped in music of chinese/japanese origin, a few booths and tables, never a ton of people. Some things can look bad, like the blinds that just seem to get grungier.
The normal meals and plates that I've tried are usually just OK - the sushi is where it's at. I could do soup and sushi here every week, no problem.
