My Canteen in King's Lynn and West Norfolk

We have been to the Pera Grill on several occasions before and have had excellent service and food. Our latest visit was not to be so. Ordered food and drinks promptly, a little wait for the drinks but doesn't matter, when the beers arrived they were 0% alcohol, when we questioned the waitress she asked was we sure this was the case and had to point on the bottle's label. Then we waited and waited, saw tables being served, eat their meals and leave, still waiting, no bread and dip, no asking would we like more drinks- actually had to go to the counter and ask. After a wait of nearly 1.5 hours approached the counter to see what's happening, was told why are we complaining as we've only been here 30 minutes...errr no. Finally food came out - parts were cold, had enough by then, offered to pay for the drinks and were leaving, didn't want us to pay for anything and just leave. The impression we got is that those cooking could only deal with 1 table at a time and were extremely slow even dealing with the 1 table. It's a real shame as have previously enjoyed going there and have recommended to others.
