Decided to do a "Jewish Xmas" ... Chinese food and a movie. Wish we had skipped the Chinese food. First and last time at Great Wall. My Vegetarian Lo Han was simply tasteless. Walked out with a stale taste in my mouth and couldn't wait to find desert or something sweet to clear my palate. The menus are labeled "15% gratuity added" but the server could not seem to clarify if our bill included the gratuity or not. We left a 20% cash tip and paid the bill at the front counter. The proprietor took my bill and cash payment, slipped it into the drawer, and started serving other customers. I had to ask for my change ... and added 'tip left at the table' in case there was some confusion. That was awkward at best and cheating at worst. Will not return.
