Subway

Food is good as in any other Subway, so you can choose a lot of type of bread and different meat. The best part of this particular Subway is the workers, none talks to others because everyone knows what to do. They are also very very precise with customers, I keep on eating here for them (besides of food)
Even if there's long queue you don't have to wait long.

DO NOT GO HERE. They only show the 6 inch prices on their screen and nowhere does it show footlong pricing (which is A LOT more than normal Subway). On top of their extortionate prices, subpar sandwich and poor service. Do. Not. Go. Here. The burgers across the hall are £7 and way better.

The customer service is non-existent, the staff are clearly just trying to rush you along, not actually following your order. The drinks are lukewarm and tasteless - unless you like Pepsi flavoured water.

The prices are extortionate even for London, considering you’re paying for a bit of bread.

Avoid, avoid. They get your order wrong and don't give you all parts of the meal deal. Asked for no cheese, they put cheese on half of a footlong, terrible for lactose intolerance, wrong type of bread, didn't provide crisps with meal deal, tried to object and was just ushered along. Utterly terrible for £10. Find somewhere else.

They shout at you, chuck whatever they want in your sandwich and then give you some cola flavoured water!

Customer service? What customer service!

I’m sure that the only reason this place sees any business at all is because it is in an exhibition location that probably never serves the same person twice, and because people probably don’t read Google reviews before they visit these places. If it was your local Subway you would visit it once and never return. The prices are diabolical. The food is poor. The staff can be heard bickering amongst themselves as they serve customers.

Avoid this place at all cost. Wrong order, wrong ingredients and when I told them they put in wrong sauce they just removed salad to get the sauce out and put new sauce in and wrapped it without any salad or cheese left. When complained they just make face and stuff the salad back it and gave it back just like that.

Never more! I have been here when Drag Con was happening. The service was really fast, but they did not ask me if I want the meal reheated or what type of cheese I want. The tables were full, had to sit on a floor. The meat was old and dry. Dont go there!
