Eating out can often be a dieter's nightmare with diners unable to control calorific content or portion sizes.
But a new pop restaurant in London's Soho seems to have created an ingenious solution for foodies who want to watch their waistlines.
The restaurant, Size Matters, which will be at the Sun & 13 Cantons pub in Soho for the next eight weeks, offers traditional British dishes from its 'size matters' menu in small, medium and large.
Size matters: Burgers can be ordered in small, left, medium, centre, or large at the pop up restaurant
The restaurant is run in collaboration with Piccadilly Circus' The Criterion Restaurant, with their head chef, Matthew Foxon, creating the food including mini British beef burgers and fish and chips. Starters, main courses, desserts and side dishes can all be ordered off the menu in various portion sizes.

A spokesman for the restaurant told the MailOnline: 'The idea is to give the guest greater control over their portion size, you hear a lot over the internet about portion sizes and how difficult it is for restaurants to get it right, so we thought it would be a good idea to put that choice into the guest's hands.'

How hungry? The small burger is bitesize while the large includes three pieces of meat
Of course the range of sizes also means a range of prices. A small main course such as a British beef burger costs £8 while the medium is £11 and the large £15.50.
The mini burgers and hotdogs are bitesize - so are not likely to satisfy eaters as a main meal. Rather, the restaurant recommends the smaller portions as a light snack.
Meanwhile, the large triple burger is not intended to be eaten by just one person.

The spokesman explained: 'The large sizes are mainly chosen when there is a large group and they share everything around - the dishes work really well for sharing.
'A large portion of burgers is three triple burgers, but this is absolutely designed to be shared around - and our servers will advise of this when it is being ordered.'
As help as helping people watch their weight (provided they don't eat all of the large meal themselves!) the spokesman added that the concept has also reduced food waste.
'It has also so far proved to be a great way of reducing wastage - again, because people know what to expect and finish everything,' they said.
