Hi Stephanie, I am almost always on my own in Paris and am quite happy to be so. There’s a wonderful essay in “Hungry for Paris” by Alexander Lobrano about dining solo in Paris. I guess I read it before I started really traveling solo often, and I find it to be true. Waitstaffs in Paris tend to be very welcoming to the solo traveler (least this has been my experience). I will sometimes have a book or be listening to one, but often enough once the food starts coming, I usually just enjoy the restaurant vibes and theater.
I will say that my last couple of times at Clown Bar, when I was solo, it wasn’t such a friendly experience. It’s near where I stay, so I might give it another chance (as the menu is often appealing). I’d be curious how you find it as a solo traveler, if you go.
Le MaZenay is my favorite local (to me) bistro, partly because it is such a comfortable place to eat. There is a bar, but with low back stools, it strikes me as it might not be so comfortable, so I just go ahead and book a table. It’s a square room, so wherever you sit, you are able to see the room. I would feel comfortable eating game, etc. here. It’s a changing menu (the one online is just an example), but last time I was in Paris I had pigeon one night and a sole meunière the other night (starters were string beans w/mushroom and a Vietnamese slant on musslels)–all delish!
Also last time I was in Paris, I sat comfortably at the bar at Korus (thank you @SteveR) This is a tasting menu, but you can opt for a slightly shorter version (or the longer one). I’m not usually such a fan of tasting menus, but this one I found creative and tasty. The waiters were all incredibly warm and friendly, and the sommelier put together a wine tasting for me that meant I could still walk home after the meal. I ate the larger meal, and though full, didn’t feel overly so. I’ll go back.
I went to Jeanne Aimée the first time solo; again was welcomed and treated well. They placed me so I could see the open kitchen. I don’t know if they did this on purpose because I was alone, but it was a treat. This is probably the most creative, modern food I’ve had in Paris in recent memory. I wouldn’t miss this! (Open Monday nights)
L’Amarante is about as different as you can get. Very old school, meat heavy. But well prepared French classics (all those edgy bits you might be looking for). No real decor, but again, comfortable, and they welcome me whether I am solo or with a friend. Also, it is open on Sunday and Monday nights. Useful.
Finally, a brasserie is a bustling place for people watching, I find, and I ate (only once) at the newish Grande Brasserie on my own. Nothing edgy here, but quite good food, and excellent profiteroles (which I adore). N.B. Leave room; it’s a humongous portion.
I haven’t eaten at any of the places you mentioned, and would love to hear your recommendations when you return! I am booked to go to Granite (thank you to @andygottlieb42) on my next trip. Hope you have a swell time!
P.S. Don’t forget the crèperies…some (most?) are open through dinner (I’m thinking Breizh and Gigi in my Paris neighborhood). Sometimes a light something just hits the spot. Ditto for an oyster bar…
