Is that your staying in Brombourgh on the wirral? odd choice?
Anyway as said above it depends on age & what your into… Friday or Saturday?
Being from Scotland, I doubt you will find any part of the city centre rough, Ive been to Glasgow, Ayr, Dundee, Aberdeen! Nothing to worry about! 😉
Victoria Street end of town as recommended, Smarter side of town with regards to bars, maybe harder for a Stag do to navigate though.
Concert Square is other side of city centre. Very mainstream, Walkabouts, Reflex, Lots of commercial mainstream bars & the people that come with it! its a love hate area only you will know if it suits or not
St Peter’s Square area, Just up from Concert Sqaure, Contains Bars called Peacocks, New Revolution, Igloo, Alma De Cuba, then up the road, Mojo & Heebie Jebbies which are open until 3-4am.
I would recommend the St Peter’s Square area for a stag do & for friends, its the best compromise & from the listed Bar’s there is something for everyone!
Note… As with most places, large groups of lads wont get it, something you can’t avoid, really is strict sometimes, so you will want to go upto doors in 2’s-3’s max to be safe! Annoying I know!
If your into a late one, Nightclubs, several options, my choice would be Garlands / Bedlam, G-Bar, Passion, all in the victoria street / Dale Street area.
