Murf, depends what you want to do.. City Centre is a 5-10 minute walk to SSE. McHugh's is probably the last pub you get to before heading over the river to SSE (assuming you are staying in the City Centre). Its ok, and likely will be busy.
However there are other great pubs in town, The Duke of York, The Harp Bar, The Garrick, Muriels and Kelly's Cellars all worth a visit,
City Centre is a bit messed up at the minute due to fire in store right in the centre of town, which has effected traffic flow.
You will have a great time..
Want any more info drop me an IM
