Considering England is the "Home of Fish & Chips" I have had some of the worst mutations of this dish here on Her Majesty's very own shores.
Having read great reviews of Olley's I decided to check it out. It's located near Brockwell park, which serves as a great spot to eat your battered sea creature and chips on a nice day.
They do a lunch deal from 1PM to 3PM, £6.50 for Fish of your choice, chips and mushy peas. I ordered the Haddock. The Haddock was great, covered in a very nice batter that wasn't feral or out of control with oil and other anomalies. Tasty chips to accompany. I'm generally not a fan of mushy peas, but these had a very gentle home-made taste to them, if a bit bland. A splash of vinegar spruced them up. They are ultimately better than the offensive processed varieties.
Olley's do their fish grilled too if you're not into batter, however why is it that you can't find any breaded fish in most Fish & Chip joints in this country?
A good cheap eat at £6.50.
