Terrible foodand horrible service

I purchased 2 vouchers from Wikideals and redeemed them on Friday past.Upon arrival we waited to be served for drinks for more than 20 minutes and two family’s arrived after us and they also had vouchers and were a family of 7 members and the other 2 members.They received there food very quickly which was also the burger special and milkshakes or desserts.We then waited more than 45 minutes for our burgers to arrive and that time the family of 7 and the other couple of 2 has already left .We ordered a nacho’s as a starter which we eventually got very dry hardly any cheese with very little condiments too when asking the waiter why all he said why it’s comes like that chips very dry over baked .Eventually we got our burgers which the chips was cold and the milkshakes was watery.While waiting we already had a crawly visitor a ****roach and reporting this to the waiter all he rep**** was they fumigated the kitchen the Thursday evening
