Leading the way are the "boutique" chippies, such as the late lamented Tom's Place, where you can usually get your ethically sourced fish grilled, pan-fried or steamed. Here are six of the best.
The Fish House, 126-128 Lauriston Road, E9 (020 8533 3327) Mon-Fri noon-10pm, Sat & Sun 11am-10pm. Large cod and chips, £9.50 eat-in, £6.50 takeaway.
A modern restaurant that retains the traditional layout — fryers and takeaway counter to the left, eat-in to the right. The basics are done well here, crisply battered cod, good chips and mushy peas. Plenty of more ambitious options ranging from tuna salad Niçoise to whole sea bream.
