Great seafood but be aware of sharks!

Found this fabulous seafood restaurant La Grilladin in Porto Vecchio - Corsica and we were having such a great time watching the chef at work and enjoying the food. That was until the bill came! 200 euros of which 90 euros was for a piece of fish that we shared!! Okay so it was the catch of the day and it was John Dory and it did weigh 106grams before filleting but bloody hell they could have warned us I nearly fell off my chair! Note to naive self : get fixed price for all dishes served before consuming..flipping heck!
