Butter Avenue never dissapoints me. I initially came here for macarons because I had a macaron phase. They offered unique flavors and the macarons had different fillings besides the usual ganache at other places. They also rotate flavors so it's nice once you've become accustomed to their regular ones.
The entire aesthetics of the place is beautiful. Simple and clean. They also have a small seating area downstairs for those who wish to enjoy their treats instead of takeout. It's actually a nice quiet place you can get some studying done too. The A/C wasn't quite strong enough on the day I had gone though (although it might be due to the fact that it was incredibly hot outside).
Their cakes are also amazing. I love the green tea mousse one. I thoroughly love all things matcha, and this one had an intense matcha flavor and the brownie at the bottom was sweet enough to balance out the bitterness.
10/10 would recommend and i'm looking forward to coming back here to try their other pastries too!
