Abbeville has a nice aerodrome eatery - nothing exotic but clean, friendly and well-priced.
I don't know where you'd be flying from, but I used to do an 'experience building' flight for those who wanted something different. Route down to the Sarrf Coast west of the London TMA, over the channel and land at Abbeville for lunch. Then route via Dieppe, east of the TMA and land at Stapleford for a cuppa and perhaps some fuel - not just to spot all the Essex girls and the 'diamond geezers wiv' wads'! Then back on the Lambourne to Bovingdon 2300' rat-run north of the TMA and back home.
The flight was a good intro to cross-channel requirements, French customs, GPS-assisted VFR navigation, radio aids work, grass aerodromes and busy airspace. A good summer outing!
