The only hot food available at Hampden for the remaining Glasgow ties is a variety of pies – mince, steak, curry or cheesy bean.
The rest of the menu has been restricted to crisps, chocolate, fizzy drinks, tea and coffee.
The prices have also come in for criticism. A pie and a standard fizzy drink will set customers back more than a fiver.
Even on the Hampden concourse, the options have been fast food outlets selling burgers, bacon rolls, chips, curry sauce and hot dogs.
Chips, normally available at Hampden, cannot be sold in the stadium because of the Olympic sponsorship by McDonald's.
Olympic chiefs banned all 800 food retailers at the 40 Games venues across Britain from dishing up chips because of "sponsorship obligations".
In comparison to the limited fare in Glasgow, sample menus of the food available on the Olympic Park reveal a host of options, from carrot and cucumber sticks with red pesto hummus priced at £2.50, to pole and line caught tuna and sweet potato salad for £5.90 and jacket potatoes with chicken, bacon and salad for £5.80.
Advertising had advised fans at all venues to expect a "great variety of food and drink" in venues "from filling meals to tasty treats".
Consumer Focus Scotland has joined fans in criticising the choice of food available, which they feared give a poor impression of Scotland's eating habits.
A spokesman for Consumer Focus Scotland said: "It's a huge opportunity missed to showcase good, healthy Scottish fare.
"Pies will always be part of the experience of visiting Scottish football grounds, but it wouldn't have taken much for Hampden to raise its game by offering a much wider taste of Scotland to visitors during the few weeks when it is at the centre of the world's attention."
Brian Jeffrey, 22, from Uddingston, South Lanarkshire, who went to Hampden with his five-year-old son Jamie, said: "I was disgusted. There really were no options to eat, for either me or my son at all, and we had to make do with basically unhealthy rubbish. I don't know why they didn't go the whole hog and dish out deep fried Mars bars."
Another fan blogged: "Considering I was locked in the ground for five hours to watch two games the options for eating were awful, and the queues ludicrous."
The key aims of London 2012's food vision were to "ensure we offer affordable food that offers choice and diversity, and we have healthy food and can cater for special dietary and cultural requirements too".
The organisers also boast of winning several awards "for our work in supporting and promoting sustainable food procurement and the British food industry".
Jacques Rogge, the president of the International Olympic Committee, has previously admitted there was a question mark over the sponsorship of the Games by McDonald's and Coca-Cola amid concerns about growing obesity.
However, he said the introduction by McDonald's of healthier menu options and Coca-Cola's zero-calorie drinks was evidence of their taking public health seriously.
Fast food giant McDonald's have four restaurants in London's Olympic Park, including its biggest in the world, which can seat 1500 people.
All soft drinks and mineral water were to be provided by Coca-Cola, including Innocent smoothies and juices, and 75% of the drinks Coca-Cola expects to sell at the Games will be water, juice or sugar-free.
A spokesman for the London Organising Committee of the Olympic and Paralymic Games (Locog) said: "The menu on offer at Hampden Park during the Olympic Games football was designed by Locog to meet the London 2012 food vision, including Red Tractor accredited produce and reduced fat and salt."
