We stayed at the Alvear, and the tea was by far the most oversold and underwhelming experience. If you've had proper tea in London or The Imperial in Delhi, this is downright shoddy. The cups were chipped, the servers kept banging things against our glassware and the desserts looked average at best. Good people watching though, it was full of BA's ladies who lunch. The teas themselves were fine, as were the finger sandwiches, but nothing to rave about.
I don't know if non-guests can have breakfast, but if so, then the breakfast buffet L'Orangerie is MUCH better. The tea service does not do justice to the physical space of the L'Orangerie. Or, trade up and go to Bourgogne at the Alvear. The tea experience is not worth the time or money, and if you've had authentic tea at similar places elsewhere, this is totally meh.
