As if Jill and Michael Leviton didn’t have enough going on these days what with the addition of new baby Isadora, they’ve just announced the addition of a $35 prix fixe menu available Sunday through Thursday evenings at Lumière. The three-course menu, which will change weekly to take advantage or seasonal goodies, has featured apps like onion soup with gruyere crouton and chives or country terrine. Entrée selections have ranged from red wine braised beef with winter veggies and horseradish aioli to chicken fricassee with mushrooms, onions and bacon. Save room for desserts like the lemon sorbet with winter citrus salad or the (this is why we love Jill and Michael) “Ode to Brigham’s” hot fudge sundae. And just to make it easier for you, they’ve even decided to open on Monday nights, so swing by to say congratulations, stay for something to eat.
