Hey
Guwahati has lot of temples if you would like to visit.
the most famous one is "Umananda temple" on the peacock island on Bhramaputra river. smallest river island of the world. You will need to reach early around 9 am or so, as it will take at least 2 hrs to complete darshan due to all time rush. if you want you can go for vip darshan for 400rs
Then you can either visit a zoo and botanical garden together or skip and visit Ashram garden. if you would like to go for shopping then you can visit fancy bazar. you can also visit the planetarium if you are interested.
hope this info was helpful.
There are many temples in guwahati like kamkhya temple and many more please google on it and visit them, dont keep more than two places in one day span at guwahati
You can choose amongst these: the famous Khamakya temple, Bhramaputra river cruise, Pobitora wildlife santuary, Saulkuchi, Assam State Museum or Guwahati Planetarium.
You can visit the zoological park which is approximately 2km from Ganeshguri flyover. u cn take local bus which takes around 5-10 rupees.
u can visit Kamakhya temple, but i would suggest you to visit umananda temple, which includes a boat ride. the croud is massive sometimes so choose the time properly. you cn visit Chandubi lake for a sunset.
Must visit Is Simanta Sankardev Kalakhetra. do check the entry timings. its very nice.
if you are with your gf u can visit Sandhanjali Kanan Park ,which is near zoological park.
for restaurants :
if you want to try Assamese thali, khorika and gams delicacy is a good place to try.
other good places are mocha restaurant in bhangagarh and tera maya, 4 seasons,..Also sanghai salza is also very good.
