I'm not sure how this place hasn't been reviewed before, Urbanspoon has quite a few reviews.
The concept of Market is great. A slightly upscale sports bar, yes, it's been done a million times before, but not in RR. The servers at Market are fantastic, but the bartenders are a joke. Unless you're a rich guy from Westlake or Avon and the bartender has seen you a hundred times, expect looooong waits for another round. Incredibly inattentive and inept, I've left empty glasses and 20s sitting in front of me for as long as 15 minutes before someone noticed. The Reuben I had was tough as leather and not very good. I went back for brunch and the food was pretty decent... I think it depends on who's working in the kitchen. Better management would make this place really take off.
