I like a hash brown but I prefer fried potato slices. or B&S.
referring to mushrooms as "mush" makes me feel ill. Mush on toast. No, you're alright ta.
Cafe Ole
155 Falcon Rd, London SW11 2PD
I often pop in for a small fry up but they do large Full English and other dishes. It's not mega old school but is a nice environment.
