I am jealous and hope you have a wonderful time! Don't pass up this great opportunity.
One small warning....some of the tea there can be malted, which is a no-no! Just make sure to check the labels or ask if it's plain tea. Also, some of the bread can contain wheat starch, which is like gluten lite. It's accepted over there but many of the brands do not contain it. I ate bread there and just checked to make sure it was safe. The bread I did have was quite good.
