Sounds good to me, all I can think of is nandos in the retail park or one of the quieter car parks/levels in lakeside it self ten have a wonder to the boardwalk. Or there's the Dog and Partridge in North Stifford or the Harvester, the trouble with them is its Sunday roast dinner day so could be busy or lack parking.
R32OC used to go Frankie and Benny's in the retail park but it's not all that in there.
