On Haštalská in Staré Město, Onesip is a tiny espresso bar with a low counter, a couple of window seats, and most customers spilling back onto the pavement outside. The street is quieter than the main Old Town drag, but the stop still feels fast. That balance is what makes Onesip worth the shortlist: you get serious coffee in the middle of Prague without the visit turning into a production.
Coffee
Espresso and filter both matter here, and the filter is a real reason to make the detour. Onesip works with Candycane coffee, keeps beans on the shelf to take home, and has the kind of compact menu that lets the bar stay focused. If you want a flat white or cortado, the milk drinks are clearly part of the rhythm too, but the point of the place is still the cup itself rather than a long list of options.
Food
Food stays in support. There are sweet and savoury pastries, croissants, and good hot chocolate, which is enough to round out a quick stop without pushing the room into brunch-cafe territory. This is a place for coffee first, then a pastry if you want one, not the other way round.
What people go for
The room
The room is too small for a long stay and better for a stand, a short chat, or a seat by the window if you catch one. Service has enough warmth to keep it from feeling transactional, and that matters in a bar this compact. If you want space to settle in with breakfast and a laptop, look elsewhere. If you want one of the sharpest coffee stops in the centre, this is it.
Why Filter Notes has shortlisted Onesip Coffee
Onesip is shortlisted because very few central Prague coffee bars are this small and this dependable at the same time. The room is minimal, the seating is tight, and the whole visit is over quickly, but the filter, espresso, pastries, and takeaway beans all feel well judged. For a coffee-led stop in Old Town, it belongs near the top of the list.
