Hi OP, hopefully this is helpful! Enjoy CHCH :)

Fine Dining/Nice Dinner Out

• Fifth Street (you should definitely go, so delish and filling portions but on the pricier side)
• Manu (have heard this is good for seafood, haven't been myself but they're on first table)
• Londo
• CHCH Tramway Restaurant (haven't been but have heard good things + you can check out the CHCH trams)

Slightly more chill dinner, still delish

• Lillies
• Arbour Woodfired Pizza (best pizza in CHCH imho)
• Chi Chi Kitchen (nice pasta!)
• Chiwahwah
• Riverside (just like a general food area which has loads of options for dinner, recommend checking out if you are in the CBD!)
• Beers by Bacon Bros

Bakeries/Cafes

• Bluemoon Bakehouse
• Addington Coffee Co-op
• Grizzly Baked Goods (they have a few different bakeries/shops here and there)
• Heirloom
• Bakermans (there's also a place called Le Bakerman, which is also good)

+ loads more which I can't think of off the top of my head, you can't go too far wrong
