I was happy to see that. There is NOTHING open on Sunday night in Greenville--I hope they keep it up.
My past experience there: my bf and I arrived just before closing...yes, we were *those* people. A lot of restaurants give mediocre service around closing time with hardly anybody else dining, but the staff was fantastic. They genuinely cared, asking if we liked the food, what our fav rolls were, etc. While Sushi Masa & Purple are the top-notch (far away/expensive) choices, I'd go to Sushi Koji any day before Tsunami. It's great sushi (and noodles!!) that won't break the bank.
