We went to Convito Cafe and Market, a great place with a nice market with gourmet foods attached to a restaurant with an Italian and French menu. Convito is a result of the merging of two restaurants by the same owner - one was a French Bistro and one an Italian Trattoria.
They have a terrific gluten free menu - with tasty salads, white bean soup, a great steak, delicious salmon dish, polenta and mussels and more. They will also prepare some of of their other dishes gluten free if you ask them. They sell a lot of gluten free items in the market - like rice pasta, parmesan crackers, and a huge variety of their frozen sauces that are ALL GLUTEN FREE! We had a pleasant experience while visiting family in the North Shore of Chicago, and look forward to going back. They were so accommodating when we told them we needed the gluten free menu, they were very careful to make sure everything we asked for was perfect.
