Really Disappointed
Today we had my daughter’s birthday dinner here ,
The whole night was horrible, we have been comming to this location for a really long time , years
Today to celebrate my daughters birthday the service was beyond slow, food was not the same as it normally is smaller portions and crapy quality. My vegetables were soggy. My pasta just kept breaking everytime i picked it up, my order and my husbands order was wrong. My chicken one piece was burnt . My dads pizza was a size for a child .
Unfortunately we will never return . To beat it they dont even sing happy birthday anymore to a child??
My daughter was looking forward to that .

I have been to this specific establishment many times. All times have been sub par or good enough at best. This time.....an amazing experience. Best experience at any restaurant. And i believe it stems from our waitress. Layla i believe her name was. She was fun, attentive and knew how to joke around and made us feel like actual guests. If i return, no questions about it she must be my waitress. Thank you for the amazing hospitality!

Started off badly, was told a 25 min wait for a near empty restaurant and pretty sure we were forgotten about when another family got in after us but was seated first.
Food was good, and server did her best but clearly this place is understaffed. We had no cutlery or napkins until after bread and salads came because we simply were not a priority.
Soured a special evening. Badly run restaurant it seems. Won't be back to this location again.
