good steak tartare is tough to find, recently we enjoyed it recently at Leopold in Chicago:

slagel heart of ribeye tartare | $16
shallot, caper, farm egg yolk, frisee, whole grain mustard, chef's toast

meat was finely chopped.

With some good Belgian beer, Mrs Sweet Willie & I were 'yumming' it up, our waiter had a chuckle as I guess we were being a bit noisy

(and if you go, get the main entree of the smoked rabbit, out of sight!!)

We have a number of very good Middle Eastern restaurants in Chicagoland, I'm looking forward to trying some lamb tartare next time I go to one.
