The place is quite close to the city center and to the bank of the river Tisza. It is not an official devotee place, however the decoration highly suggests that it is related to the religion. I think it is a family business, the mom cooks and her daughter serves the food and takes the orders. Not sure if English is spoken, however it is very likely. I have not seen an English menu, worth a try asking for one.
At least half of the dishes were vegan, there is a daily menu as well. I had a fake goulash soup with seitan which reminded me of a simple vegetable soup, nevertheless is was fine, lacked a bit of paprika powder and was too salty for me.
Second dish was a chickpea-aubergine sabji with rice which was okay, again too salty for me.
Paid like 4-5 euros for the 2 dishes and a lemonade.
All in all, I was very happy that I could find a place where they served vegan food, however I think the chef needs a bit of practice with the spices.
Cons: spicing of the dishes
