Avoid! Horrible service, average food, over-priced, long waits... fails on virtually all levels.
Much better food around Portobello than this.
S & M is very much part of the Portobello culture – a regular hang out for the Notting Hill residents as well as market visitors. The ethos is unpretentious – what you see is what you get: big portions of great quality traditional British grub, friendly service, a relaxed and informal environment and a small bill.
