Falafel in one of those cheap West London places must be one of the best bargains in foodville. If you get it right (not always the case), you're getting proper falafs (fluffy warm nutty pillows, not crunchy bullets or tasteless pap), strips of pickled turnip, strips of gherkin, tahini, harrisa, torn parsley, some salad and a wrap - for £3!!! and bloody delicious at every bite.
