If it's good weather, the walk around Bristol harbour is a nice way to shake off a hangover. Make sure to stop off for a coffee and a bacon sandwich at Brunel's Buttery.
Lots of pubs worth a visit. Especially 'The Apple' if you love cider
Do a great Sunday roast!! Go for the pork belly! You just may need it the morning after!
Best Steak House in Bristol by far! Definitely need to book in advance
Great cocktail bar, look closely for the entrance
