Klassz is owned by Bortársaság, Budapest's leading wine retailer, and as you'd expect, wine is an important part of the experience here. The wine list, which is pleasantly brief, consists almost entirely of local wines, and offers many good values (try something from Gellavilla, a winery run by one of the owners). Located on Andrássy út, not far from the Opera House, Klassz is a cheerful place, with bright floral wallpaper, a mega-high ceiling, and a bar in the middle that's been made from stacked-up wine boxes. During the warm months tables are set up on the sidewalk. The brief menu changes frequently, and is a mix of international bistro–style and modern Hungarian. Soups, which may include a consommé with chicken liver dumplings, are served in copper pots. It's not always easy to find a proper salad in Budapest, but Klassz always offers several on its menu. Foie gras, sautéed duck breast, and Mangalica pork are all things the kitchen does well. Desserts usually feature seasonal fruit. Or opt for a glass of the sweet Tokaji aszú wine, a dessert choice that can't be beat. Klassz doesn't accept reservations, so be prepared to wait around for a table if it is a busy night. It also functions as a wine shop, and all of the bottles on display in the back of the restaurant are sold at retail prices.
