7.2 Rainettes (the other word for frogs in French), 5, rue Caron in the 4th, 09.86.59.63.85, open Tues, Weds, Thurs dinner and Fri, Sat, Sun lunch; (Metro: St Paul) is one more in the long line of mono-maniacal (as Figaro would say) restaurants, following Rouge (Tomate), Pommes, Cochon Gaulois, Boeuf Maillot and others I've forgotten, along with the oyster places - Istr, Bar a Huitres, L'Huitrier, etc. that tend to feature one product front and center, albeit also having other items as well as Yankee-food-focused Maryland crabs, BBQ, hamburgers, hot dogs and such. As you enter there is a huge patch of vertical moss, etc., as there is over the stairway downstairs. In a rather small space are lots of stools at high tables but a few regular tables and chairs. The "menu" is a startling 19 E for 2 course; 22 E for frogs' legs; but I wanted the whole deal so I went a la carte.
I started off with the frogs' legs beignets which were glorious, especially with the crème fraiche/ciboulettes and spicy tomato sauces; followed up with splendid frogs' legs provencales (that is, butter and garlic) with black rice; and to finish an (unpictured) crème renversee (Pop-Quiz; what was the name of the cook in French in Action who served it - remember, she was a "pearl")? All of it went down very well with a Pic St Loup.
Now, my bill with a half-liter of wine and fine bread and coffee was higher than necessary; a couple with a bottle of wine and no bottled water could easily exit for 119 E. dB's were only 77.8 because the wonderful English-speaking wait-lady turned the American music down.
Go? You must. Who doesn't like frogs' legs? And if you don't there's salmon, duck breast, beef, etc.
