“Walkable” and “grid” are orthogonal concerns.

London and Tokyo are two examples of very walkable non-grids, which I prefer to American grid-based city planning — the random connections fuel serendipity.

I think the problem in modern suburbs is really fortress-like unconnected developments, which also appear in urban form as overscaled block+ monoliths. The Metreon in San Francisco is a good example, or the ugly “italianate” Geoff Palmer apartment blocks around downtown Los Angeles.
