HARVEY'S -- 1001 18th Street, NW. 833-1853. AE, CB, DC, MC, V. Reservations suggested. Full bar.

Tradition. At Harvey's, it's big drinks and big menus, big portions and big prices. It's also a big restaurant, an underground labyrinth of tables, booths and bars. The wonderful parts of Harvey's are its broiled stuffed fish: whole flounder, rockfish and trout are impeccable to start and flawlessly cooked. There are nice touches, among them good warm bread, inventive vegetables and refreshing salads. Fish'n'chips with toasted muffin and soup du jour $6.25 at lunch only.

JERRY'S SEAFOOD -- 9364 Lanham-Severn Road, Seabrook. 577-5161. AE, CB, DC, MC, V. No reservations. Full bar.

Jerry's Seafood has taken a long detour, but it's back in its original spot in Seabrook, and serves extremely good spiced shrimp: large, juicy and spiced just enough that you can still taste the shrimp under the seasoning. If you like your seafood fried, Jerry's is your place. The batter is puffy and crisp, the seafood under it fresh. The service is homespun, breezy and chatty; it is friendly Prince George's County at its best. Fish'n'chips with salad, vegetable, roll and butter $4.95.

MY BROTHER AND ME -- 1700 K Street NW. 296-6686. AE, C, CB, DC, MC, V. Reservations accepted for parties of five or more. Full bar.

This basement room looks and sounds like a disco: dim lighting, low ceiling, little globe bulbs and a mirrored wall. Fish 'n chips with coleslaw $4.95.

OCEAN IX -- 1323 Fenwick Lane, Silver Spring. 589-0999. AE, MC, V. Reservations suggested. Full bar.

Finding, a block off Georgia Avenue, this charming single- family house, which has mushroomed into a homey restaurant, should be enough of an accomplishment. Discovering that it serves mostly seafood and generally fresh seafood at that is more than one could hope. The baked or poached seafoods in sauces are far better than the broiled fish. Fish'n'chips with vegetable and beverage $8.50 at dinner only.
