NOT: $ Grills & Martinis, Exmouth Market, Clerkenwell

Exmouth Market is a nightmare to navigate on a cold rainy evening if you're not familiar with it, so I was grumpy to begin with. Inside didn't help matters - slow service and uninspiring food. My burger with 'sweet potato, feta cheese, rocket and herb polenta' ended up being a burger bun with a patty containing said sweet potato, feta cheese etc, plus some limp iceberg lettuce and a slice of tomato.
