Lindey's was one of my favorites. It's been eight years since I lived there, but here are some places I liked:
Trattoria Roma (Grandview) - very good Northern Italian
Bexley Monk (Bexley)
Moretti's (near Dublin) - underrated Italian, never seemed to draw a big crowd, I hope it's still around.
Martini's (one right between downtown and the Short North, I believe there is another one near Polaris)
Barcelona (German Village) - maybe not the best place for a group, but very nice.
Thurman's (German Village) - HUGE burgers
The Short North always has good restaurants - I liked Snappers for seafood, Haiku for sushi, Rigsby's was good as well. Not sure where you're staying/playing but based on the courses you're playing you might be nearer to the Polaris area which I'm not as well informed about (it has really exploded since I left - for instance, I was not aware that Lindey's apparently now has a Polaris location).
