On day 2, Ju Yon made reservations for us at a tiny yet somewhat formal restaurant called Ribouldingue, one of the most memorable restaurants I have ever had the pleasure in which to dine. Their specialization is offal, and it is unbelievable how good it can taste and feel. The food here was mainly about texture.
Here is what it looks like from the outside:

It’s a tiny place on a tiny street (more like an alley), so you probably won’t find it unless you are looking for it.
Before we ordered our dishes, we received a large amuse-bouche. We still are not sure what it was that we ate, but it was tasty and covered in paprika.

You can see the jelly-like texture. There wasn’t much flavor to it; you noticed the texture more than anything else.
I photographed Ju Yon’s absinthe, because it was prepared the “proper” way:

Sorry the pictures are so dark and grainy: it was dark inside and when I took the first picture, the flash made all of the other restaurant patrons jump, so I turned it off. The glass had a small amount of green absinthe at the bottom. The hostess provided a spoon with holes that was placed on top of the glass, and placed a sugar cube on top of the spoon. She handed Ju Yon a tiny pitcher filled with clear liquid, which Ju Yon poured over the sugar cube, causing it to melt into the glass. You can see that it became cloudy. Although I am still not a fan of absinthe, this was much better than the absinthe I tasted in Prague. Of course, I took the absinthe in Prague straight, and chased it with packets of sugar that Val and Monique had brought from a cafe.
The menus were in French only, and so Ju Yon, Jason and I had to rely on our past years of French to decipher the choices. As we hadn’t spent much time learning about offal, we mostly had to guess based on the few words we did know, and even then, we weren’t sure what would appear before us.
I ordered a dish which read “something of pork, served on a bed of lentils,” which sounded good to me. When the waitress brought out my dish, I could see quite plainly that a pig snout was sitting atop a bed of lentils.

It looked quite horrific, but I bravely cut into it with my knife and was surprised at how easily and smoothly it slid through the meat/cartilage/muscle. It wasn’t rubbery, although it looked rubbery. It was more like slightly firm fat, but almost melted on the tongue with a bacon flavor. It was delicious. The lentils complemented the smoky bacon flavor perfectly. I would order this again in a flash.
We had the same confusion with Jason’s appetizer. We could decipher “veal” and salad. It sounded delicious, so he bravely ordered it. This is what arrived:

As you can see, it resembles thinly sliced beef flank. It reminded me of thinly sliced pork belly, slightly crispy, with lean meat and bits of fat, but no pork flavor. It was delicious, and we still couldn’t tell what it was. We all enjoyed it. After dinner, when we returned home (4 hours later), Ju Yon grabbed her dictionary and looked up this dish. Turns out the word we couldn’t decipher meant “cow udder.”
Ju Yon’s dish was the only one deciphered properly, and it was lamb tongue… we think…

It was delicious. The softest tongue I have ever eaten.
For my main dish, I understood what it was that I was ordering… mostly. I ordered head of veal, and I had no idea what to expect. I wasn’t sure how much meat would exist on a head, or where the meat came from. Was it going to be the cheeks? Were they going to scrape the meat from around the skull and just toss it onto the plate? Here is what surprised me:

Yes, it is what it looks like. You are staring at the brain of a baby cow. It is disgusting to be staring at it, when it is obvious what it is. I was brave enough to taste it, and I ended up finishing it, but I wouldn’t order brain again. I wish I had taken a photo of the cross-section when I cut it open. The inside was creamy white, solid, the way it looks when you cut into raw tofu or raw mozzarella. The texture was like flan, but the flavor was strange. It tasted all right as you chewed it up and tasted it on your tongue, but as you swallowed it, there was a strange sour aftertaste, like cream cheese or sour cream. The taste was fine, but the aftertaste was unsettling and sour. I didn’t like the aftertaste, so I’m not sure why I kept eating it.
The best part of the dish was the head itself:

Do you see the steak on the back of the plate? That was one of the most delicious things I have ever had. It was like braised short ribs in the form of prime rib, only the meat was more tender than any shortrib. There was a good deal of good fat surrounding the meat in a ring. Words cannot do the dish credit. Just trust me that “veal head” is a very good thing. But skip the brain.
Here are the kidneys that Jason ordered, I forgot from which animal:

They tasted like slightly gamey seared liver, but a little more steak-like. Jason was asked how he wanted it prepared, and I believe this is prepared medium. One of the things I miss about Paris is that the French never, ever, overcook their meat.
Here is Ju Yon’s tripe:

It looks like a delicious stew, and it tasted like a delicious stew. I love tripe. It came with wine sauce and herbs and vegetables, and it was a nice, comfortable, country-tasting dish.
Jason ordered French toast for dessert:

Yum!
I had coffee-flavored chocolate pot de creme with a madeleine:

I could probably eat this almost every day with coffee if I had the choice. The pot de creme had such a great texture and fluffy-to-thick ratio.
This is Ju Yon’s rice pudding with orange marmalade:

You can see the jam jar next to the plate. Ju Yon got to scoop the amount of home-made marmalade she wanted to add to the dish. It was a good ratio of sweet to bitter.
We spent 4 hours eating and drinking and having a wonderful time. We were one of the first to arrive for dinner, and the last to leave. Although the place had a slightly formal feel, the servers were extremely warm and made us feel at home. The restaurant had a nice volume level that allowed you to speak at a comfortable level, without shouting to be heard and without making you feel as though you had to lower your voice. Actually, every restaurant in Paris was like that.
This was one of my favorite dinners in Paris. I would definitely come back and do it all again. Just without the brain.
