    The restaurant accepted my reservation, and took a £20 deposit. When I arrived, the restaurant was closed!

    Sadly we had a really poor experience here. It looked so nice on the internet but honestly the food was so poor. The lamb sheesh was pretty cold and chewy, my husband was ill after the chicken sheesh. The service was strange. I'm not sure what this place was trying to be, but it didn't work for us. Had we not been entertaining clients I would have complained and sent the food back but it was awkward to do that with clients. And we had to pay a £40 deposit! We will never use this place again, its the same pricing as some really excellent places in the area.

    The booking was done and the resultant was closed. Major embarrassment to turn up with partner and her dad. This was on top of the fact that they took a deposit of 30 pounds. I will be raising a formal police complaint and going to the onbusdsman. How is such a property even listed here. Amazes me. Bedi
