This is what I send people in work when they ask:
The Ulster Museum (which does a bit of everything),
Botanic Gardens,
Queens Film Theatre for arty films,
Lyric Theatre for plays,
The lagan towpath and fields is a nice walk along the river too
Slightly further away but still in town there’s
the Titanic Museum (I’ve never been but I hear it’s good),
The MAC (art exhibitions and plays etc),
Western europe’s biggest glass dome in the Victoria centre (lol but true apparently),
We have bikes you can rent now apparently too!
For food I can only think of
Clement’s Coffee shops,
Boojum’s (burritos, quick and cheap and really good),
Maggie Mays on Botanic (I’m slightly hesitant about this one, it’s cheap and basic burgers etc but definitely a bit of a Belfast institution),
Little Italy (cheap, take away pizza),
Villa Italia (pasta and pizza basically, been there for as long as I can remember),
Morning Star (pub grub),
Greens Pizza
If you fancy spending a bit more $$$ for eating out
Flame,
Made in Belfast
Bars and Pubs (can’t remember if you like to drink but it doesn’t matter, some of these will do food and traditional irish music too if you fancy it):
The John Hewitt, The Sunflower, The Duke of York, Muriel’s, Laverys (does pool and rock music upstairs) and The Spaniard.
This might be a bit out date/wrong because I’m not there very much these days, icarus has probably covered much of it too.
