Some of my favorite lower key downtown bars are:
Barrymore's
Miller Time Pub and Beer - at the hotel
Ramo's Pizza- next to Church
1867 Bar
Zoo Bar
Jake's Cigar and Spirits
O'Roukes Tavern
**I haven't checked that these are open. If all else fails, head to the Haymarket and Brewsky's won't let you down!
If you need a snack or want a cold beer with a dive bar vibe, I would recommend Ramo's Pizza. Located on 48th and Normal it is incredibly close to the church!
Yia's Yia's - Pizza
Picklemans - Pizza and Subs
Tico's - Mexican
Canyon Joe's - BBQ
Sultan's Kite- Mediterranean
Bison Witches - you won't be hungry anymore!
Miller Time Pub and Beer - This is at the hotel
