I got a map of Budapest and marked out on the map where all the vegi/vegan restaurants were. I did this with the help of searching 'Vegan' into google maps and of course with happycow.net. This is a very handy way of knowing what restaurants are near by. There was always options nearby the major attractions!
Breakfast was the only tricky part. I'm not much of a breakfast person as well. So breakfast consisted of bread, Starbucks and some fruit. Eden Vegan restaurant on Buda Hill do a vegan breakfast, but we didn't make it over for breakfast.
I stayed in the amazing Corinthia Grand Royal Hotel, Which was amazing! I never get to stay in very luxury places but we got a good deal so why not! The room service menu and the various bar/restaurant menus were very accommodating to those with allergies. Each dish stated if it contained eggs, diary etc. This was great to see. I had pasta on the first night.
Now down to the food. We were luckily located a few blocks away from Napfényes Étterem vegan restaurant. I had a great experience here and the food was great. The menu is available online so we were able to have a little look before. They have loads of vegan pizzas but I had a horrible cheesless pizza that day that was enough to put me off pizza for a while. I wasn't that hungry but I over ate anyway! Don't think I had ever eaten in 100% vegan place before. I went for the ''Fried Pancakes Filled with Vegetable Cream served with Mashed Potatoes and Onions (spelt wheat pancakes filled with spicy vegetable cream served with fried, mashed potatoes and savory tomato sauce)'' and finished it off with some sugar free choccy cake!
Located at the foot on Buda hill is Edeni Vegan Restaurant.
The location is quite great, it's located right beside the Batthyany Terace metro stop which is on the red line. It is also located at the bottom of buda hill which is home to many many attractions. It's about a 10 minute walk up to the hill. So very convenient, you can grab a vegan breakfast before setting off to Buda castle or you can enjoy lunch after a morning of exploring. Down to the food, I'll be honest in saying that I can't really remember what I had but there was a great selection to choose from, including desserts and smoothies.
