La Maison Navarre
The owners of La Maison Navarre really want you to feel and taste Paris. They have designed their cafe after traditional Patisserie Francaise and Bar a Vin in France, crepes included. They have a gluten-free batter to make crepes, but they do not use a dedicated pan for them. This place is still worth a visit just for the experience, but if you cannot afford cross-contamination, just stick with the wine and macarons.
