Not exactly a "macaron" expert but I have had a few over the last year i.e Nadege, LaBamboche, Bobette and Belle.
Space: Love the clean fresh decor.
Food: Sampled a few macarons and can't complain. However I really really loved their roasted almond tea. Absolutely delicious.
Service: Lovely.
Would definitely meet a friend for tea and a macaron at Butter Avenue!!
