I will answer my own post, having just had a terrific lunch there.
Max and Benny's opened on Tuesday (for lunch only). Tomorrow will be their first day for breakfast, and in a few weeks they will open for a full breakfast, lunch and dinner schedule.
This is a very attractive restaurant of some 180 seats--tables, booths and a bar area in front. It is located in the River East AMC Theatre complex on Illinois, on the ground floor, with a street entrance one door east of the theatre.
For my first venture, I wanted to try the basics. Matzo ball soup, corned beef on rye, potato pancake, and a black-and-white cookie for dessert with coffee (by Intelligensia).
Soup was served very hot, a nice chicken broth, and a medium-sized, medium density matzo ball. The corned beef (which I ordered lean instead of regular) was just right, not greasy, piled high on what seemed like a double-baked rye reminscent of Langer's in Los Angeles. I might try the regular next time, which is the right way to have corned beef vs. the oxymoronic lean version. The latkes were a bit of a disappointment, having a flat, almost pre-fab appearance. They tasted okay, but were nowhere the robust look and feel of Manny's. B&W cookie was great, with a Yin Yang icing scheme.
All baked goods are brought in from the Northbrook location each day, and don't seem to suffer from the journey.
Despite some first week miscues (had to ask for water and mustard), the staff was enthusiastic, if slightly out of synch. I don't think it's a team waitstaff approach, though it seemed as such with all different people taking the order, running food to the table, and refilling my Diet Coke (which I ordered after I found out that the only Dr. Brown's they don't have is Cel-Ray).
All in all, a delightful place, and I'm thrilled Chicago finally has a very good, Jewish-owned deli, right in the middle of everything.
