Eat and drink in U.K. as a miser. 節儉吃喝在UK.

I think U.K. should be one of  the most expensive place in Europe.( But also Northern Europe and Switzerland)
我想英國大概是歐洲數一數二高物價的地方。(除了北歐與瑞士)

And in my personally opinion, the British food are not so yummy.. especially breakfast...
The acceptable food you can get ( in restaurant ) is fish and chips,taste not bad and not so expensive.

另外英國的食物真的是不敢恭維。尤其早餐...

餐廳裡面比較便宜又能吃的只有薯條與炸魚(fish and chips)。

So most of time I always choose cheap food as my energy source.

所以大部分我都與便宜食物為伍。

The following list are where you can find your best friends.

以下是你的商店好朋友

Tesco Express: Everywhere. Lots of bread and cooked food.
到處都有，生鮮食物很多。

Sainsbury's: More than less in city center. Most of them are near to tram/bus station.
沒那麼多，車站附近找一下都會有。

Testco Superstore: Quite big but in urban. However, you can have lot of choices here.
就是英國家樂福。東西種類比較多，在郊區。

Asda: 就是英國家樂福。東西種類比較多，在郊區。

Quite big but in urban. However, you can have lot of choices here.

Starbucks: 當你已經不想喝水跟啤酒的時候，星巴克算是實惠的飲料。

If you're sick of water and beer. Starbucks is always the best option in your list. (Grande is really large. Based on the average coffee price there, it's not expensive. And free wifi and plug for your phone.)
