I love going to RiRa and it's a fun atmosphere! Downstairs is more restaurant/bar with a very large, long bar area. On some nights they have Irish music which is a lot of fun too.
They have pretty good food and I really like the Banger Bites!
Upstairs turns into a club space on weekend nights with a DJ, so that can be a lot of fun too. There is an outside patio upstairs, but I haven't been out there.
Definitely a low-key working man's pub and a solid Irish bar choice for uptown Charlotte.
