Finally tried Boule when was getting my car washed across the street. Got a bunch of macaroons and the koign amman. First off, the koign amman was excellent, although at $3 I don't see myself indulging too often (which is probably also a good thing for my waistline).
As for the macaroons, tried rose water, chocolate, pumpkin and green tea (IIRC). While they were good, I still think the ones at Jin Patisserie are better - the pastry itself slightly crisper at Jin but the real winner is in the fillings - the ones at Boule just tasted slightly off to me (maybe it was my fault for getting a pumpkin flavored one). So, Jin wins.
ps. pitching Michelle Myers against Kristy Choo makes me proud to be an Asian woman! Even thought I don't bake, so this is totally irrelevant.
