Budapest Baristas is a small specialty café and breakfast restaurant in Budapest's downtown. They serve seven kinds of bagels (yes, the boiled-and-baked version, but they aren't made in-house), including one with a classic smoked salmon topping. They're tasty, but keep in mind that Budapest is no bagel capital like Montreal or New York. There's also other on-trend international breakfast foods like pancakes, granola bowls, and eggs Benedict. Portions are on the small side — most people can easily handle two plates.
A La Marzocco machine is in charge of the espresso-based drinks, which are supplemented by pricey matchas and filter coffee. Note that depending on who's behind the counter, service can be a little testy here.
