My sister is turning 40 in a few months and I am helping plan her birthday dinner in Chicago. Suburbs are fine, too whatever fits the bill. It will be our family, and I'd like to take her some place really special. She's a foodie and a wine lover and especially likes places that do excellent wine dinners and pairings. I also want a place puts service at a priority. I know she has been to Spiaggia, Vie, Avec, and L'Etoile in Madison and loved those experiences. I've been wondering about Fahrenheit, Table 52, Moto and Blackbird, but any suggestions are welcome. It's a special day for our family since she is entering a PhD program this fall.
