Lived and worked in Birmingham from 2011-2015 and absolutely loved being there so gonna defend it. There’s tonnes of great stuff going on, it’s just often quite hidden and people don’t tend to shout about it so you need to either look it up first, or meet people who are in the know. Took me a good few months to settle when I first moved there.
Also the city itself is weirdly laid out due to all the redevelopment, and it’s tricky to get to the suburbs etc where interesting things are. Public transport was shit, basically. Last time I went the building work everywhere made things even worse for navigating, but the city centre itself is almost entirely walkable in half an hour.
Off the top of my head:
Art stuff
BMAG
Ikon Gallery
BOM
Vivid Projects
Eastside Projects
ORT Cafe/Gallery
Digbeth warehouses
Custard Factory
Millennium Point
Music/Cinema
THSH
Hare and Hounds
Sunflower Lounge
Flatpack Festival
Supersonic
Electric Cinema
Fierce Festival
Frontiers Festival
Rainbow Venues
Various warehouses in Digbeth often had interesting happenings
Food/Drink
Balti triangle and Balsall Heath for curry
All the little cafes in the city centre, often in the arcades - 6/8 Kafe, Faculty, Yorks, 200 Degrees, peel and stone bakery
40 23 - great cheap mediterranean food opposite new street station
3 Michelin Star restaurants with fairly affordable lunchtime or set menus for fancy food
Cherry Reds for food and beer
The Victoria, Wellington, Post Office Vaults all decent pubs
The more suburby areas of Harborne, Kings Heath, Balsall Heath and Moseley all had great pubs for food, interesting shops, and markets etc most weekends.
There’s lots more I can’t remember now, but you get the idea.
