All of their teas are delicious (well, of the ones I've tried). They have over 100 flavours and you can smell each one in little glass containers they have. Also, most of the teas are organic and/or fair trade, double bonus.
I've had their breakfast wrap and caramel apples before. All were delicious.
Only complaint is there is no plug, so after my laptop battery is dead I can't stay and drink more of their tea!
