David's Tea shares some store space with Le Chateau, but I was assured that it's only a sublet relationship (obviously this is a question they get a lot.) David's Tea differentiates itself as a more laid back place than Le Chateau. David's plays laid back jazz tunes, for example.
As soon as I walk in, tea shop employees look up with a smile. I'm not sure if this is because I'm their first customer in a while, or because they're genuinely nice people, but I don't think about it too much. Their tea of the day is available as a sample, a tiny shot glass of tea. Then they got into talking. The staff I spoke with was very talkative and very excited about tea in general. Telling her I steeped tea at home earned me a nod of approval, and when I asked that she recommend a tea, she had 3 for me to smell very quickly. The tea itself wasn't the greatest, but there are dozens upon dozens to choose from, and that's bound to happen when trying new teas.
