Hey, hope you're doing well!
YUSU (the students' union) is based in a small building in James College and the sabbs and PTOs (Part-Time Officers) work hard to represent students and of course, organise a variety of events and socials. There are 3 bars on Campus West: V-Bar (Vanbrugh), Courtyard and D-Bar (Derwent) and 1 bar on Campus East: Glasshouse (Langwith). This afternoon, there's been a huge announcement from YUSU that Courtyard and Glasshouse will have additional outdoor space which will remain there permanently and there's going to be a new outdoor festival-like space in term 1 on Campus West called '
The Forest' which will be Covid safe.
Glasshouse is a nice student bar which is of a decent size and Campus East colleges run a lot of events and socials there. The food and drinks selection is good and they also show live sports on the big TV screens. As for Campus East itself, it can feel quite quiet because most of the departments and accommodation are over at Campus West (main campus) but you can easily get around between campuses on the 66/66a bus for free. Also, colleges over in Campus East do run regular events and socials and some societies organise stuff on both campuses. My favourite bar on campus has to Courtyard because they have a good selection of food and drinks and space can be transformed for socials like Time Warp.
As for the city centre, there's quite a lot you could do such as visiting The Shambles, York Minster, the National Railway Museum, etc. and there are several nightclubs (though we've already lost a few - YUSU are proactively fighting against that): Revs, Salvos, Kuda, Flares and Society. In terms of best places for drinks in town, you could literally go on a bar crawl and visit places such as Stone Roses, Lowther, etc. (I'm not the right person to ask when it comes to organising bar crawls lol) and ofc, there's Spoons in Merchantgate.
Hope this helps!
