Rahier is an authentic French patisserie. Actually, many good patisserie chefs in town used to work at Rahier.
There are plenty of seating for you to enjoy the pastry. The ambiance is relaxing and nice to have a quiet conversation with friends. Service was polite but not friendly enough.
Cakes and tarts are the best at Rahier, and the price is very reasonable (mostly under $7 a piece); croissants are nice, but it would be even better if the staff would offer to warm them up for dining in.
Drinks are decent but over-priced.
I will definitely come back to get more cakes.
