I am looking for a restaurant in Evian that offers good cooking at a reasonable price for a quartet of unmarried senior citizens (two males, two females). We don't know each other all that well, so the place shouldn't be too upmarket (which might be off-putting or give a false impression !) but rather have a friendly ambience so that we all feel at ease.  A central location would also be helpful.

Many thanks for any suggestions or recommendations. Ritchie
