Found this hidden gem in Prague city centre (at Na prikope). They speak English but most of the patrons are Czechs! When it is hot you can sit outside on seats on 'fake' turf, all under cover with fans operating overhead! Lovely and cool on a hot day! Or sit inside a huge 'hall' if it is cold outside!Note there is only one drawback...only one ladies toliet, which didn't lock properly when I went. But that aside, great value, good food. Lunch deals each day, 2 great courses for under £3!! (on a blackboard) and also printed for a week or two in advance, if you want to experience different specials on another day!
You can have pizza or pasta deals. I loved their lasagne and went back for another day too! (It was huge and must have a black beer base for their meat sauce, as it was sweet and delicious for 129 CSK, good value too!) It is even better deal if you get it on their lunch special!
Also cheap drinks too! But get their early or late, as the locals fill it up for lunch from 11am!!
