We visited 2 of their 3 cafes in Paris. The first was a try and see as we needed food and a good coffee. They had both. The staff were super friendly and extremely helpful in every way.
After doing the Eiffel tower and before we headed to Gare du Lyon to return back to Basel, we grabbed some food and drinks at their cafe near that location, cafe Kozy Bosquet.
Unfortunately we took too long and by the time we arrived at Gare du Lyon with our baggage we missed the Basel train. Sigh. Andi was not a happy camper and so we then re-ticketed for a later train.
The result of this meant hanging out at a cafe in the train station. Nowhere near as nice or good or friendly and we were mingling with not so pleasant people there looking for unsuspecting passengers with pricey luggage that could be borrowed on a permanent basis. Jeff was on the ball though and made sure no-one got close to ours.
