Went to the restaurant last night, after only having one bite of a vegetable and realizing that the vegetable dip was actually tzatziki sauce i was completely sick. The rest of my group continued to eat while i was ill and we waited for the waitress to come with water and drinks. After 15 minutes of waiting we asked to bus girl to send our waitress over because i was really sick and we needed our drinks still. 20 minutes after this we asked the bus girl AGAIN where our waitress was. At this point i told her i was extremely sick from one bite, it was my birthday ontop of this and that i was furious that our waitress was mia for half an hour. She only gave the excuse that they were using a new system and she would find her right away. 10 minutes later she finally showed up, gave us our bill even after i said i didnt eat and i was sick we were still charged for my meal.
Worst service i have ever received. Not even a "sorry this is how we will fix this" i only got the excuse of some unknown system stopping my waitress from being in the dining room for over 40 minutes not filling water or taking a single plate away from tables. Never ever eat here.
