Croydon Steak House, CR0 1BE
Fantastic little restaurant in Croydon. The steak as you would suspect is great, as is the apple crumble.
The menu seems not to have been updated since the 70s - starters are things like tomato soup (the only thing we've found yet to not be great), liver pate, grilled sardines, egg mayonnaise. If you're not a fan of steak then the salmon is also recommended. There's one vegetarian dish but I can't remember what it is.
