HIDDEN GEMS, fun topic. Here are a few of mine
Fat Tuesdays - Southern, creole food on SW 9th just north of Army Post. Seriously, the best collard greens I have had in my life
Henry J's Tacos - Also on SW 9th, not far from Lincoln HS. Great Tacos, sides leave a bit to be desired
Angelo's Pizza - Now in the cursed building on 8th St in WDM, jusst south of 235, great pizza
Cooper's on 5th - tiny little bar/resturant in Valley Junction but tremendous food
Tacopocalypse - Now with their stand alone shop in the East Village. Go for a brunch, you will love it
Francie's - Off of Fluer, north of the airport. Not sure this counts as a hidden gem because it is pretty well known, but it's tucked off the road and tough to see. Great atmosphere for a few drinks and even better bar food.
Cosi Cucina - Italian, good date spot
Orlando's - solid pizza and good pasta dishes. Great place to stop while on a bike ride
Agree on Orlandos, great pizza, in house made sausage and the best little salads in town
I have a hard time calling any Jethro's location "hidden" anymore
