Upon entering we were told to find a table and then remember the number when ordering at the cafe. Finding a clean table without lettuce or crumbs on was the first challenge. We ordered 2 milkshakes, 1 tempura prawns, 1 beef nachos, 1 goats cheese salad and 1 cheesy chips. The milkshakes arrived quickly- the strawberry one was nesquik powder with the powder sitting at the bottom waiting for me to mix it. The food took another 30 mins to arrive and looked lovely at first until we took a closer look. The cheesy chips were an absolute joke for £4.20...a small desert bowl of 12 chips, with cheese on top that looked like they had been microwaved. The tempura prawns were vile- undercooked large ones and chewy smaller ones. The nachos were average- beef chilli tastless and not fresh, 3-5 slices of jalapeños in the whole dish. The goats cheese salad was bad- not warm like stated. About 5 half walnuts, half a beetroot and 4 chunks of cucumber. Basically a bowl of leaves and again quite tastless- not what expected for £16.95! We asked for ketchup and Mayo- the Mayo bottle was filthy with fingerprints and black marks. We asked for water and were told they wouldn't be a minute... 20 minutes later no water so we left. We watched a server place a cup of tea on another table to free his hands whilst serving. But he hadn't been told the table was out of order and there were no signs. The table toppled over and the tea spilled everywhere. Had a customer sat down at the table they could have fallen and hurt themselves. £47 wasted and left very concerned that we may be ill since eating undercooked prawns. Such a shame when it's such a lovely location on the water.
