I arrived in this place with restaurant.com certificate and they refused to accept them telling me that they didn't understand the contract that they had to offer $5 with a purchase of $10 so they give me a 10% discount instead. Feeling bait and switched, I saw a dish in Chinese that I liked so I said no problem so give me the Sour Vegetable with Chitlings as well as homemade yogurt. The lady took my $15 dollar and asked me want any change back? First of all, change are automatically given and it is extremely tacky to demand a tip from me. The meal is $12.45 and want a 20% tip even before the service is rendered? I told her to give me $1 back. She told me this is her first day on the job..Forced and demand a tip? ..May be the fact that I also Chinese but this type of behavior is totally unacceptable where I came from and even it is unheard of in USA. The meal is decent with excellent knife skills and taste great (****) but being bait and switched, forced on paying a tip, and not even a thank you at the end of the meal earned yourself a two star rating from me.
