The ambience is zen like and cozy so be sure to keep your speech volume the same. An employee did come up to us telling us so and not very politely because we we giggling (too loud). Seriously, bring you whisper voice with you. They also discourage the use of cellphones and other mobile devices.
As for the tea, it was amazing. Ha the Le Boréale and the aroma & flavour was great. So much so we had a second round in which they just added more water to the pot and still the flavour was there.
Good place for a first date if the plan is to meet over some tea.
