If you feel like ordering a nice croque monsieur or maybe even madame...?
This particular café is exactly what you need when you are looking for when you are walking around Paris or when you want a break from anything bad or annoying which might have happened during your day. If it has been the case, I highly recommend you to get a café gourmand.
The café gourmand in général in a parisian café is often on the menu and is a good alternative to ordering an actual dessert. This café, at le Lutèce comes with a selection in small portions of the desserts presented onto the daily menu.
