I just got back and we stayed in the Jordaan neighborhood for a few days. We ate at the following places and had a good time. All of them are relaxed, not-fancy places. The wait staff all spoke English, but I don't recall hearing much English from the other patrons.
Cafe de Doffer was where we ate on our first night. We sat outside, so I'm not sure what the seating is like inside. I had the best (maybe it was the best---maybe it was the first meal that was not from an airplane) chicken satay w/ peanut sauce. mmmm There is a website.
Billy Thai's was right next to our apartment and we ate there one day after sooooo much walking. I may have started out as a lazy choice, but it was tasty! It's on the canal (there is a website, too, with a menu), and has some outside seating, but we had to sit inside.
On the way to walking down to Westerkerk nearn Anne Frank house, we got ice cream at a great place--I wish I knew the name, but if you walk down the canal street that AF Huis and Westerkerk are on, you'll see the line!
Also, there is Cafe Molenpad. We only had a cheese plate and a beer/wine here, but it also has tables on the canal-side.
Really, if you're in the Jordaan area, you will walk past so many cafes with tables set out on the corners, by the canals; almost all places have menus posted outside, so you will just have to choose one. Or, you can always find an Albert Hijn grocery and pick up a few things and sit on the canal wall with your legs hanging over and eat there! :)
Oh, I miss Amsterdam so much!!!! Have fun.
