Glad you like it so far, wondering what you'll think of your experience on the small railway.
Seeing as you've done the fancy Hungarian history side meal, I'd recommend for contrast Pivovar Hostinec (brewery inn in one of the oldest continually running hospitality locations in the world) or if you are feeling more fancy, Café Slavia, more of a brasserie vibe but excellent food.
Or for something totally different, Ohnisko
