Cafe 403, W4 4AR
Decent greasy spoon cafe in Chiswick. Has two levels of seating, one at ground floor level (about 18 seats, all fixed-position) and one down some steps. There was a TV on showing the news on the lunchtime of Bob's visit.
Only offers one set breakfast. Bob went a la carte, with egg, bacon, black pudding, tomatoes (fresh, fried), chips, and tea, which came to £5.70 photo. It was all good except the sausage, which was just your standard greasy spoon mystery meat version. The black pudding in particular was very good.
They also do food other than breakfast food, most if not all of it fried, e.g. scampi and chips.
