We had a 3:00 late lunch on Saturday in early October of this year.    We figured it was later in the day, thus explaining the emptiness of the place.  By that, I mean, we were the only ones there. Towards the end of lunch, that hadn't changed much.  With the \"Best of LV\" reviews I've read previous, I was rather surprised there was no other customers.   Knowing this was a bad sign; we were parched and hungry from earlier activities and ventured inside.  We ordered the papaya salad, chicken on a skewer, pad Thai noodles, and a grilled pork plate.   Every dish we ordered was bland and lacking in \"wok hei.\"    What is that you ask?  Wok hei is the Chinese term describing the fragrance of food that is cook correctly in a wok.  Also, it's a pet peeve of mine when drinks we ordered were served in plastic cafeteria cups.  I'm not 10 years old and am certainly not paying cafeteria prices.  After a $50 lunch bill for 2 adults and one restaurant phobic child, we were told that restaurant is under new ownership and would not accept the Restaurant.com certificate. The whole reason we even tried the place was because of a Restaurant.com certificate. Needless to say, that was our first and last time dining at the Mix Zone cafe.  Restaurant.com customers beware because they still offer the certificates to this restaurant on their site even after I notified them of the problem.
