Streamline Espresso is a cafe trading from the Epiphany Church carpark at 54 High Street in Solway, Masterton, and it holds a 4.9 rating on Google.
Small coffee stands in carparks are a New Zealand institution: no fit-out to speak of, just the quality of the shot and the person pulling it. The flat white is the local yardstick, and a stand that keeps its regulars tends to be one that gets milk texture and consistency right, day after day. Setups like this live on commuters and daily regulars rather than passing trade, and they often keep their own hours rather than a fixed shop schedule, so it pays to check before making a special trip.
For Masterton locals and anyone passing along High Street, this church-carpark stop is a highly rated fixture on the Solway coffee run.
