Boulogne La Matelote, 80 Blvd Ste-Beuve (00 33 3 21 30 17 97). Mon-Sat lunch, dinner daily. Boulogne's most expensive restaurant is grand, well-established after 19 years, and just over the river from the ferry terminal. Not, of course, for cutting-edge cooking, and with menus at Fr175 (pounds 18), Fr235 (pounds 24.50) and Fr355 (pounds 37), or a la carte at around Fr300 (pounds 31), it's not cheap, but guarantees against disappointment. Turbot is a speciality.
Dieppe Le Marmite Dieppoise, 8 Rue St-Jean (00 33 2 35 84 24 26). Tue- Sun lunch, Tue-Sat dinner. Down a side street, this typically homely restaurant has for more than 30 years specialised in the dish that gives the restaurant its name, a selection of seafood: sole, mussels, langoustines, brill, monkfish and scallops poached and served in sauce with potatoes. Most people have this and the warm tarte aux pommes for Fr175 (pounds 18), but you can eat less for from Fr100 (pounds 10.50).
