I was in Debrecen in 2018 on an acting course trip. 2.52 I walked past that many times on my way back to my Air BnB. Nice city, wouldn't spend too long in it though
You, my friend, just missed out the most part of Debrecen. First of all, you haven't noticed behind yourself the lovely park which calls "Nagyerdő" which is actually the most famous natural phenomenon around Debrecen. You have found a couple of restorants but they mean the less. Next time when you came to visit our city just ask me as a guide and I garantee that you won't miss out anything.
