There's nothing at LIG, you check-in then go through security and downstairs to the "holding pen" and wait for boarding. There is a toilet in the holding pen and I think there may be a drinks/sweets machine of some sort but nothing else. There's a coffee shop in the check-in area and a paper/sweet shop.

It's my local airport and is mainly used by Ryanair and Flybe with some Air France flights to Lyon and Paris Orly.
