I am born and raised in Southern California. I've eaten in countless Vietnamese restaurants in Orange County especially the Garden Grove area that is one of the Meccas of Vietnamese in the United States. As a vegan my options get limited but not as much as one might think. So I scoped out my vegan/vegetarian options of restaurants in Prague. My Airbnb was in 7 and this place was close. The Prague market is close so I grabbed my fresh product there but that got old and I needed a home base restaurant so I would not eat the ubiquitous amazing smelling fried meat and cheese extravaganza that is literally everywhere. And so I stumbled into ZAU and my trip to Prague became amazing, First off. Vegan is half of the menu. If eating animals and animal product is your thing then they will take care of you. For me it's not. There is an everyday buffet. This is staple food. Actually there is a tad more to it but more on that below. That buffet food kicked ass. ANDCHEAP. It's so cheap that I was felt morally obligated to unload the five pounds of pirate coins (Czech peeps love coins and you will end up with a pirate treasure pile of coins) that I had collected in the Czech Republic. I ordered some vegan Thai noodles and it was some of if not the best I'd had. So i made friends with the two women who run the place. They are from the North Vietnam area and have been in Prague for awhile now. I recommend learning a bit about WHY there are so many Northern Vietnamese natives in the Czech Republic and the story of how they answered the call to go to the Czech Republic when there was a worker shortage. One socialist country helping another. Vietnam figured they would come back with experience and skills. They had kids born there and lived working the hardest low paying meager jobs. After 1989 they stayed and instead of just working at a business they began to start one. They took the YEARS of knowing how a d what kind of Vietnamese food western folks typically enjoy and developed those. Which means you are not going to get something funky unless you ask for it. Everything up on the board is tried and true Vietnamese fare. Holy shit it was wonderful. And then I noticed the Vietnamese (always from the north areas) all over the Czech Republic. North of Prague they have are everywhere. The backbone of the service sector they have been tenacious in securing a better life and take great pride in the businesses they operate. I will miss my two temporary Vietnamese mothers who fed me everyday when I lived in Prague. So go. And tip them well. And listen to them speak about how they got there.
