Yes, this Beroun restaurant has a loyal following. It’s very hard to get a seat in its tiny dining area. Many say it’s the best. Once again, I’m gonna go against popular sentiment. Blackdog’s burgers have the potential for greatness, but they have a major flaw as far as I’m concerned. Their menu specifically says all burgers are cooked medium unless otherwise requested. I always confirm that this is how I want it with my server. And every single time I visited (and I’ve been many times), the burger came well done. The thick, rounded patty was dried out to its core and hard to chew. If you haven’t had this problem, well, I’m jealous. On the last visit, I had the 140 gram Black Dog Cheeseburger (105 CZK). But I had the same problem with their bigger patty, too. Their burger had lettuce, dull cheese, tomato, red onion, herb mayo, and ketchup on their bready brioche-style bun. Adding their soft, smoky bacon cost 20 CZK and fries were extra.
