That this unfussy, communist-era neighborhood bar right across the street from one of Budapest's most visited tourist destinations (Dohány Street Synagogue) still exists, and hasn't become the victim of commerce is a small miracle. Despite its moniker, Turiszt Büfé, which opened in 1982, has never gained much of its business from tourists. I can't tell if the name was meant to throw sand in tourists' face or this was the best they could come up with at the time.
The wall-to-wall wood paneling lends a warmth to the tiny space, and I always find it a weirdly magical moment to sip here a €1 beer with the picture postcard view of Europe's biggest synagogue bathed in light before me. A range of wallet-friendly "bottom-shelf" wines, bottled beers (two also on tap), spirits, and snacks are also served here Monday to Friday. The place rarely swarms with people, but the patrons are a combination of aging regulars and students from nearby colleges.
Before you leave, take a look at the vintage sign above the entry, marketing Turiszt Büfé with Badacsony wines produced by a state-owned winery by Lake Balaton. Note that Turiszt Büfé is closed on weekends.
