There didn't seem to be much inside, so you have to nearby restaurants for a bite to eat.
For our outbound trip, we needed to catch a SNCF train to the nearest Italian town (Ventimiglia). We used our ticket to scan through the gate into the departure area, but was not used after that.
The train runs every 30 minutes in the morning, and we caught the 7:50 train. The track doesn't get assigned until 30 minutes or so. There were no elevators with easy access, so needed to carry our bags using stairs. Track E ended up being our stop. The train came on time. It was a beautiful ride through the coast (so choose a seat to the right to see the sights).
We arrived at Ventimiglia by 8:40, stopping at the following stations (Nice Riquier, Ville Franche Sur Mer, Beaulieu Sur Mer, Eze, Cap D'Ali, Monaco, Roquebrune Cap-Martin, Carnoles, Menton, Menton Garavan). It was open seating, and there were plenty of choices. There is no overhead racks for luggage, so had to store the luggage in the baggage racks in each car.
