The Brasserie Molière has a good location in the old town, which is the main reason to choose it over the alternatives: you can sit outside and watch the foot traffic through the historic center without having to work very hard for a table. It is a straightforward brasserie — drinks, simple food, friendly service — rather than anything remarkable in itself, but the setting does the work.
In the evenings there is often music or at least the kind of ambient noise that makes a warm summer night feel properly sociable. Come here to decompress after a day of walking the old town rather than as a destination in its own right. Order local wine rather than beer and you will be eating and drinking well enough.
