Not very honest about the bill, my granddad went there last week. He is not fluent in English and was his first time in Vegas. When the bill came, he asked what that $8.10 was for (see photo), it's written SER - Service charge. They explained to my granddad ( in Chinese) that's state tax, and the $ 4.05 (in addition) is Sales Tax. So my grand tip them another $8. See photos.
