The Treats chain is/are usually found on the platforms of some London Underground stations or at least are very very close to the tube stations if they are not on the platforms themselves. Actually the ones on the platform seem to be slightly more expensive than the same ones just outside of stations. Here you can buy great samosas, onion bhaji's and indian kebabs (very traditional food in England - believe it or not...Indian restaurants are the UK's most popular eating places). Also do a full range of sandwiches, crisps, chocolate (fortunately not just Cadbury's) soft drinks, sweets and icecream. Some of their cakes taste a bit heavy on the bicarbonate of soda, but their muffins are pretty good. I used to live on their tuna and rice salads every day for lunch and some also do curries. Treats are definately cheaper than any of the food you can buy from stalls at the mainline London Railway stations and their food is a darn sight tastier than Boots rather plasticy sandwiches.
Benjy's is another chain which is actually loads cheaper than Treats but you won't find any of these on the platforms of tube stations. Look out for them if you venture outside of tube stations and you'll find they are full of Londoners buying lunch or breakfast. They have very imaginative fillings in their sandwiches (crabstick, tomato & Thousand Island Dressing, Mushroom and Brie - that is imaginative for the UK), and you can also get filling in focaccia, french bread, ciabatta and granary baps as opposed to standard pre-sliced white or brown bread. They also do good salads and babyish puddings like jelly (jello, if you're from the US) and custard, bananas and custard, rhubarb and custard and trifle too. Also a good range of hot food in the form of toasted sandwiches, bacon butties, Heinz soup and pies.Let it be said here and now,
The Infernal Chocolate Machines
I hate Cadbury's chocolate. Call me unpatriotic if you like, but it's vile and this is a great shame for me, as Cadbury's seem to have a monopoly on those machines that you will find on more or less every platform of the London Underground.
Please, please if anyone from Mars or Rowntree's is reading this, can't you make a concerted effort and try to steal this contract off Cadbury's.
