From my past experiences with this fast food restaurant, the best advice that I could give you is to avoid it. Let me give you an example why...

I happened to be passing by an outlet of Burger King when I saw a rather attractive sign advertising a special offer for a very reasonable price. So in I went...alas, I was told that this offer "did not apply to this outlet" to which I asked the point of displaying such a sign to which I was met with a shrug of the shoulders. I went ahead and ordered the food anyway, and ended up paying something like £4.80 for a basic meal, which consisited of a burger, fries and a coke. I was disgusted at this price, and they are certainly not the "King" of burgers either, as in my view they taste better at McDonalds.

At McDonalds, you can get virtually the same thing but for a couple of differences...the food is a lot nicer and the prices are a lot more reasonable. Now I only ever visit Burger King when I absolutely have to, and more often than that find myself going that extra mile in the car or taking the extra walk around the corner to get to McDonalds. Avoid this restaurant!
