Late Weeknight Dinner in Rochester, NY
Both are within easy walking distance of Eastman and are open until 11:00.
Edit - Oh dear, I just noticed that you said weeknight! They are only open until 10:00. Hmmm. Let me think. Everything here shuts down at 10:00 -- I see Nathaniels Pub is open late (that's in Cornhill) - call and ask how late they serve food.
Triphammers claims they're open weeknights until ? - they have fabulous food but it's a little pricey - I'd call and confirm that they'll stay open for you.
And here's another idea - Cafe Cibon on Park Ave.
