halfway restaurant suggestions please

We live near Vic Fezensac & have friends in the Landes (Geaune/Aire Sur l'Adour). We are looking for somewhere midway between us for moh's birthday early December, which offers a bit more than the €12 menu de jour - which would usually be fine, but we wanted somewhere with a reasonable menu with more of a choice for a celebration. Any ideas or suggestions? We don't know the restaurants in Riscle or Nogaro, but they would perhaps be an obvious halfway destination? Any personal recommendations welcome. Thank you. Ali
