Margaret and I discovered the bar/caffeteria Oblate a few years ago. It's on the second floor of a library which at one time was a convent.
And it is practically across the street from our b&b. One can get sandwiches and pastries and coffee there, as in a standard bar.
However, from Tues. to Sat., one can get hot food or salads at a very cheap price...And no service charge! The menu changes each day.
The quality of the food is quite exceptional. And also the quantity. See above...the bowl of lentil soup was enough for two.
