No, I do not think you can assume it is kosher. I am sure there are a slue of reasons for this, but I can only think of three...pardon me, but I'm new at viewing the world of kashrus, so my few reasons will have to be all I can offer you.
1. You should NOT assume that just because a restaurant is vegan that all it's cookware was purchased new for this restaurant's use. Take myself as an example, I know I'm not a restuarant, but I once ate meat, only to decide to convert in a city that offered no kosher meat at its markets. What did I do about this? I went vegetarian. Simple enough, right? Well, knowing so little about kashrus at that time, I didn't know what I could/should do about my cookware. Translation: I ate parve foods on trief dishes. Don't take anything for granted.
2. Do you care if the cookware has been toiveled or not? This is an aspect of kashrus, unless I am mistaken.
3. BUGS, and I don't mean bunny! I believe I read that you are in Eretz, are you not? Well things are different there, to be sure, but still...not everyone is going to check/wash for bugs according to kashrus.
I don't know if this is a random question meant to ponder, or if this is something you really want to know more about. If it's a random question, it is a good one...one I use to ask myself all the time. If it is something you wish to know more about, I would recommend that you talk to a rabbi. Answering questions is a rabbi's job.
 

It was more of a discussion question, and I have to say your points are pretty much the ones I brought up in the original conversation. The topic was traveling to places without significant Jewish population and eating out (well, eating in general). It was a very important question to me when I was visiting Hungary, too, and my safest bet was a macrobiotic diet!
 

I can understand that. When I first thought of converting, I read that living as an observant Jew would be difficult, but I had no idea just what that meant until I found myself smack-dab in the midst of no-where-ville, and no kosher restaurants in sight. As it is, I've relocated to Austin for an Orthodox conversion, (where I was before, there was only a Reform and Convservative synagogue, and I did the Conservative thing for a while), and despite my thrill over an Orthodox community, there still isn't much here. If I didn't know how to cook at home, I would starve.

BTW, thanks for the add!
 

We used to live in Cork, Ireland for a while, where my mother is from. There was a striving Jewish community there in the 40's and 50's but by the time we lived there I don't think there ever were enough Jews at the same place for the minyan. My dad learned how to slaughter chicken and that was the only meat we ever ate. Moving back to Yerushalayim was such a sharp change for me!
 

WOW, you're only the second Jew I've ever "known" to live in Ireland!! I'm being serious too. The last guy swore that Irish Jews were still Orthodox, even though there might have been all of 40 Jews still there, back when he left, some 25 years or so ago. (Sorry, I know that isn't what this thread is about, but it blew my mind to read that your' mother was from Ireland.)

Kudos to your' dad on the chicken; that's something I would never want to do. I don't think I would ever be able to eat meat again if I had to slaughter animals for my own food. As it is, after 3 years of vegetarianism, I find the smell of raw meat quite gross. Man...hat's off to your' dad!
 

To be honest, that was the best poultry ever! My mom raised them and dad slaughtered them and they were fresh and wonderful, non of the chicken factory cr@p sold in supermarkets. I want to learn the trade (art?) as well, who knows when my family ends up in a situation when it comes handy?
