In Paris now - need dining recommendation near Place St Michel

Cafe Med on Ile St Louis, 77 Rue Saint-Louis en l'Île, 75004 Paris, France. Small,
so you may have a wait, but 3 course prix fixe for under 20 EUR. Go past the
cathedral over the Pont Saint-Louis onto the island and you'll be right there.

Brasseries des Arts, just down rue St Andre des Arts from Place St Michel.
Prix Fixe is 39 euros, but inlcudes a drink

I'm not understanding "not deal with a reservation". Usually better service and better table when I reserve.

Anyway, Cafe Panis across from Notre Dame has a nice menu including some excellent dinner size salads.

I had a very decent meal at Le Clou de Paris about 6 weeks ago.

I reserve all restaurants. If a restaurant is worth your time, it is worth reserving, even if you are solo. Reserving allows the chef to prepare his service, is generally considered the polite thing to do, and saves you the time of aimlessly walking around looking for somewhere to eat.

If you are willing to make a reservation, spend at least 40€ to 50€ per person without drinks (pretty much the average now for a "proper meal"), I could make a number of recommendations of locations I go near St Michel.

If price point is the defining factor, there are a number of dining locations along rue St André des Arts or rue de la Huchette and surrounding area where you can dine at lower cost and without reservation.

I'll add a second vote for Cafe Panis. We've eaten there several times for both breakfast, lunch and dinner in 4-5 visits over 12 years.

It is directly across from Notre Dame with an incredible view. We've never been denied a table if we hadn't reserved. The meals have been consistently good and reasonably priced. The bonus for me is that Square René Viviani is directly across the street and diagonally across from Notre Dame. It is a sweet little park that also contains the oldest tree in Paris, benches, flower gardens and sculptures. Very close by is Shakespeare and Company if you choose to go there or wander by. A bit further behind Shakespeare and Company is Odette for cream puffs. The area is very appealing. Unfortunately the Fontaine Saint-Michel at Place St. Michel is undergoing maintenance, so it cannot be seen. I did wander a bit further to see a Wallace Fountain which I enjoy.

Another gem is Au Bougnat @ a 10-minute walk from Place Saint-Michel, behind Notre Dame. The inside is old-world charming, casual and the food very nice. We've always had reservations, but I don't know if they are actually necessary.
I hope you get the answers here that you came for.

Most restaurants have a menu posted outside or you'll see the plate for the day ( Le Plat du Jour). This serving could be a lifesaver if you're on a tight budget. Just make sure you translate and understand what it says or you might be eating kidneys or cow brains, unless you love eating that. Unfortunately Paris has been food dumbed down and those great plates with sauces are beginning to get harder to find. Good luck. Don't forget that the house wine is usually a Burgundy (Pinot Noir). Not bad for the price of a glass and last I heard the French can make a pretty good wine. LOL!
